Sorry. Little meeting. Good morning. Today on the call besides myself, we'll also have Formula One's President and CEO, Stefano Domenicali; and Liberty's Chief Accounting and Principal Financial Officer, Brian Wendling.
So let's begin with Liberty SiriusXM, where we received a $70 million regular dividend from SIRI in the second quarter, which was tax free. We also repurchased $93 million across the LSXMA and K shares from May to July and a look through price on a SIRI of $2.88 per share. We do understand the discount is widened and it is frustrating. And while the decline of LSXM is in line with the overall market, further widening of the discount has been very disappointing. We still believe repurchases are attractive means to capture that discount, but it's becoming clear they are not enough to collapse it on their own. We are focused on this.
While not a fulsome list, potential actions we might consider include: reducing debt at LSXM to enable a combination and a not overly levered SIRI LSXM; steps to better illuminate the value of our live stake and other potential actions. I would remind you at Liberty Media and some of our various spun off entities, we have a long history of corporate actions to capture discount. And these include structuring the GCI acquisition in such a way it was mid-lane ATB, the DIRECTV, RMT and subsequent sale to AT&T and the subsequent -- the separation of Liberty Expedia and subsequent merger with Expedia. In summary, we have options and actions we have taken, and we have a history of doing so.
Let me turn to SIRI itself, which I believe is handling the market challenges well and maintaining their financial guidance despite a reduced sub guidance due to a weak SAR, which has been well documented for reasons like chip supply issues. They had robust financial results for the second quarter, including revenue up 4%. Churn steady at 1.5% and new and used car penetrations up to 84% and 51%, respectively. We also announced extensions with important automaker partners, including Mazda and Mitsubishi. We made continued progress on our connected TV platforms like Amazon Fire, Android TV, LG and Roku. We signed a new agreement to fully integrate a launched a SiriusXM audio experience on Xfinity with Comcast with video to come. And on-demand music listening in the SiriusXM app is up 41% year-over-year, and that's partly driven by the addition of new, unique and diverse content. Overall sports listening is up in the app. Our agreement to make SIRI exclusive third-party platform for NFL games is helpful. And keeping the family, we also announced an extension with F1 to cover every race on the world championship calendar.
Lastly, we're very excited about our continued work in podcasting. Americans listen to audio up 9% last year -- podcast audio up 9% last year, and our podcasting and off-platform business revenues were up 50%. We also expanded our agreement with ComScore to release AI-powered podcast audience targeting capabilities.
So returned to Live Nation, which announced very strong results. It is clear live events are back on a global scale with yet another quarter of record results versus 2019, AOI is up 50%, free cash flow was up 72%, and that rose to $379 million. At Ticketmaster itself, AOI was up 86%, and the transacted GTV was up 76% again over 2019. Sponsorship AOI was up 81% over 2019 and important new clients included Google, AWS and Hulu. We had the highest quarterly attendance ever over 33 million fans and our on-site fan spend growth continues across all venues.
We have an outlook for a record of 2022 with 100 million concert tickets already sold. Fan attendance up 13% at operated venues and almost 30 new venues in the pipeline and the 2023 artist pipeline is the largest we've ever had at this point in the year. So exciting stuff.
Turning to Formula One Group. F1 continued to see record attendance and viewership in the second quarter. The Austrian Grand Prix was our second sprint event and viewership was up 39% versus the 2021 Austrian qualifying. We're also benefiting from the return of coverage on CCTV, boosting our audience in China. Similarly, we've had record in-person attendance. Four races this year have had over 300,000 attendance with incredible demand for the Paddock Club. The Hungarian weekend attendance, for example, with 290,000 was the largest ticketed sporting event in history in Hungary. So we've seen strong ticket sales and sell-out demand for the rest of the year and rest of the calendar as well.
The new regulations that were part of the Concorde agreement are succeeding and enabling closer raising and demonstrably more overtaking. We are continuing to pursue trailblazing work around sustainable drop in fuel and regenerative engine development. and we think these will have implications across the entire transportation industry. Turning recently -- to our most recent work in Las Vegas. We completed the land purchase at the foreign corporate level. We're excited about the potential for this property. We do expect to have year-round activations on this site, the main paddock building, which is estimated to be 900 feet long, with the length of 3 football fields will be exciting, and we're actively working with potential commercial partners to expand our opportunities there. We are building out the F1 team in Vegas across sales, marketing, race operations and more. We are leveraging local expertise and talent as well, including the LVCVA and our partners at Live Nation.
We are still working through the specifics on capacity. But I'd note that our founding partners in Vegas, Caesars win an MGM are seeing incredible demand, and we haven't even announced the formal date. We will obviously share more details on Vegas over time. While some of you are excited, you don't have to wake up early for races over the summer break. We here at Liberty, look forward to restarting Formula One at SPA on August 28.
Turning to the Braves. They've been playing excellent baseball over the past couple of months. As of today, we're just under 600 record for the season. And since June 1, we had the best record in baseball despite a sad loss to the Mets last night. It's an exciting team and the world's halo is still driving fans in Truist Park. Braves' attendance is up 23% compared to an already strong 2019 season. We've had 24 sell-outs to the All-Star break and trending to roughly 50% sell-out for the year.
Tickets, parking, concessions and concert the Roxy are all performing well. We've had 6 All-Stars named this year, most of the team since 2011 and double the amount from last year. We just signed an extension with Austin Riley, a 10-year deal, a $212 million, the largest in franchise history after outstanding performance by Austin this season, including historic July. Alex Anthopoulos, once again, deserves credit for the moves he took to strengthen the team before the trade deadline.
We do remember how well this worked out last year, acquiring Grossman, left field, and Odorizzi, pitcher, both insurance to our lineup, adding also bullpen capacity. We want to congratulate Snitker on his 500th career win after defeating the Phillies last week. And again, we encourage you to tune in to the Mets to night. We have nothing to report today on LMAC, but we do continue to review opportunities and look at the environment -- was difficult for specs as an opportunity for us. And with that, I'll turn it over to Brian for more on our financial results.
