Last FM is good.
Rarely, very rarely on spotify it will suggest some stuff you have not heard and has not been heard by many but this is rare as it seems to always suggest the same music.
I go onto last FM and just type in a genre and search through all the artists that pop up starting from the last page working my way through. Sometimes you find some great music.
This is a good hobby for miners! I am playing new music while reading and that is what makes it a good hobby as you can do it while doing other things. Your head can actually start hurting after looking for lots of music though!>>20208
What is popular now is normally just what is marketable as an image I agree but there are some "popular" music that is good also. My idea of popular is very skewed though!
