Piano man Gavin DeGraw can't seem to forget a past love on 'Not Over You,' a song from his next album 'Sweeter.'

Degraw co-wrote the mid-tempo track with OneRepublic frontman Ryan Tedder, so it's no surprise the two hitmakers connect on a winning formula.

The song finds DeGraw in a seriously depressed place. He sings about listening to the radio while staring at a picture of his ex and wishing they could still be together.

Despite the song's sad theme, the music manages to stay vibrant thanks to lively drums and DeGraw's keys.

As we've come to expect from DeGraw, the hook is a bit more thoughtful and complex than many choruses in pop music:

"If you ask me how I'm doing, I would say I'm doing just fine / I would lie and say that you're not on my mind / But I go out and I sit down at a table set for two / And finally, I'm forced to face the truth / No matter what I say, I'm not over you."

DeGraw is best-known for the 'One Tree Hill' theme 'I Don't Want to Be,' his only Top 10 hit on the pop charts. 'Not Over You' is worthy of similar success.

'Sweeter,' DeGraw's fourth proper full-length album, arrives on August 9.
