Hey, Soul Sister by Train

Not too long ago, I happened to "discover" this band while watching CSI:NY, and the tune was pretty catchy. Train did a cameo in the show (as a band), and Patrick Monahan (the lead vocalist) played one of the victims who very nearly got killed.

I actually went to get the CD called 'Save Me, San Francisco'. There are a couple of other songs that I think aren't too bad too, like "Parachute".

Interestingly, I've discovered a few songs I liked on CSI (Vegas and NY). There are pages that lists the songs for each episode of CSI:NY here and for CSI here.
