Ultimate Live Lounge was a competition run by Radio 1 in 2009 to find the best Live Lounge performance to date.[1] Over the previous 10 years there had been more than 500 Live Lounge sessions with hundreds of artists performing their single and an exclusive cover on air. After a series of heats, three semi-finals, and a weekend-long Grand Final, BBC Radio 1 listeners chose their Ultimate Live Lounge Cover, "Stronger" by Thirty Seconds to Mars.
