Deezer
Deezer [Deezer.com] is a website that allows you to legally stream music of your choice.
There are a limited number of artists available right now, and only signed artists are listed (as far as I can tell).
There is something for everyone on Deezer with bands ranging from Lacuna Coil to The Plain White T’s to Pink to Soulja Boy.
They have the entire plain white t’s album up to listen! For free! And it’s legit!
They also have both the She Wants Revenge albums (I mentioned them in an earlier blog post, now you can listen to all the tracks on the album rather than just samples).
Go forth and listen to free, legal, commercial music!
