I find college radio to be a good curator of music. MIT radio is a mix of students and long time music lovers who DJ.

They archive shows for a couple weeks (though it’s automatic so the shown typically starts a couple minutes in). Some shows actually list the songs they play at trackblaster.

Radio Ninja I like for electronic music. They put shows up on mixcloud as well.
