Anyone have any tips on using pandora?? All my friends say if you "thumbs up" songs you like and "thumbs down" the bad ones it will eventually play stuff you like.

I have so many people telling me that it discovered songs and artists they love that they haven't heard about but I've been honest with it and it is still giving me complete crap after months....

Its constantly playing "pop" songs for me like Justin Beiber and such which couldn't be farther from my music tastes...

I'm not opposed to downloading illegal music =O I'm just way too lazy...

If anyone has helpful tips please respond!!
