I am always trying to listen to music on line for free. I have a couple of favorite sites I like.
Pandora.com
This is a great player for when you don't know what you are specifically in the mood for. It allows you to generate a "station" based on a group or song and has a large music base that includes a lot of lesser known artists.
smashitsusa.com
This site is good if you know exactly what you want to play. It plays a little commercial (5 seconds) every two songs and has mainly newer stuff, and its a gamble if they have what you want, but its not bad for free music.
blogmusik.net
I stumbled onto this site only a couple of days ago, and the verdict is still out whether or not its any good, it seems to be a player that allows you to play others music on line, but you cannot download the songs or anything like that... its not too bad.
Anyway, I was wondering if any of you had any gems out there that I haven't heard of.
