Kenny Chesney wrote 'I'm Alive' with Dean Dillon and Mark Tamburino, but he wasn't the first to record it. Willie Nelson put the song on his 'Moment of Forever' album, which Chesney also produced, in 2008.

Chesney and friend Dave Matthews then turned the tune into a duet for the country star's 2008 album, 'Lucky Old Sun;' it also appeared on his 2009 'Greatest Hits II' disc and was released as a single that same year. Chesney tells The Boot about writing the song below.

The most personal song [on the 'Greatest Hits II' album] is 'I'm Alive,' just because of where I was in my life when I wrote it.

I wrote 'I'm Alive' after my breakup with Renée [Zellweger]. I woke up one day and realized, even though I'm going through all this stuff and don't feel good about it, the outer shell of my life is really great. I'm alive. I get to make music. I've got a lot of great friends. That's the message of the song.
