"Low Rider" by War definitely needs to be on that list.
Others:
"Falling for the first time" - Barenaked Ladies
"Free to Go" - Folk Implosion
"Boom Boom Boom" - Rare Blend
"Lollipop (Candiman)" - Aqua
"Caraluna" - Bacilos
"Greatest Day" - Bowling for Soup
"Don't Give Up on Me" - Fastball
"Calc Lecture Girl" - I Voted for Kodos
"I Want You to Want Me" - Letters to Cleo
"Mirror Mirror" - M2M
... I think that's it, for now. If you need "Calc Lecture Girl", let me know - I Voted for Kodos isn't that popular yet, and most people don't have their music ... yet.
