No. 2: ‘The Edge of Glory’

Which is the better version: the acoustic or the album version? It’s hard to tell. The acoustic rendition is incredibly beautiful, showing Gaga’s true vocal talent. However, the album version has a couple of things the acoustic one does not: a rockin' beat and the late great Clarence Clemons.

Showing that she’s a fan of all musicians, Lady Gaga had the big bad saxophone player from Bruce Springsteen’s E Street Band come in and play on 'The Edge of Glory' just before he passed away.

Clarence adds a great presence to Gaga’s anthemic song, as he did for years with Springsteen. But his saxophone is just one of the reasons this top Lady Gaga song song lies so close to the No. 1 spot. Gaga penned the powerful, climactic track after the death of her grandfather. She translated this sad inspiration to create a hopeful track that speaks to anyone who's living every day like it's their last.
