I was just wondering, what are your favorite bands/singers besides U2? I'm trying to expand my musical horizon, but it's difficult and time-consuming to find some good stuff on my own, especially the older music, from let's say the 40's and 50's to now.
Any input is welcome, from well known, to less known bands, from blues to metal, even if there is a well known band with a less known song you really like, please tell me. I'll be sure to check 'em out when I've got the time.

Thanks in advance!
