What are some bands or performers for a more positive mind frame?

umm, Yo La tengo can be good fun at times. Try King Khan and the Shrines for some raw, fun garage rock! Also, you cant not feel great when you listen to a band called Dr. Dog...Think the beatles crossed with Guided by Voices.

For me, it's gotta be Rush. It doesn't matter what song I listen to, they always pumps me right up. Also, check out that David Guetta. Some of his music can make you pretty happy. His beats are great, and they are just all around awesome party songs to lift your spirits (and that's not even my type of music).

I think whether or not a certain type of music puts a person into a positive mind frame is based on the individual. However, I have only had people agree with me so far that Yann Tiersen has a positive effect on one's frame of mind. I also recommend checking out Cat Stevens and Gotan Project. These artists never fail to put me in a good mood :)
