I found an awesome mix CD on the side of the road the other day and have been able to identify all but 3 of the 22 tracks. Two of them are covers, which renders programs like Shazam! useless. I figured out the original songs, at least.

#1 - Cover of Weezer's "Say It Ain't So" featuring prominent piano and a female lead vocalist. It's by Detroit artist MoZella on her "I Will" album.
#2 - Cover of Eliot Smith's "Between The Bars", also with a female vocalist (Regina Spektor?) and prominent piano. I'm almost certain that it's not Metric, though it could be an alternate version of the Metric cover. Chris Garneau, "Music For Tourists".

I'm willing to do some more looking, I'm just not quite sure where to look. Any ideas? Both were found through iTunes and Everyday Music is holding copies of the CDs for me.

Thanks to whoever threw out their mix disk! I love it!
