This is the worst music site ever. I mean I will use it when last.fm is down. Pandora is just why to complex to use. You have to click add variety and then type in a band name and then click add and do it all over again. Last.fm allows you to build your library by typing in a band and then click add to library but wait if you go down you can click artists that are similar to the band you looked up and you click on that artist and add them. When you build up your library you can then just play it and then add bands just by playing the recommended or mix radio stations that play music based of what you like. Plus, in last.fm there are almost no ads ( that disrupt your music) and you can skip as many as you like unlike pandora where you only skip 6 songs and have like 3 ads (that do disrupt your music). Last.fm is the best music site ever.
The Pandora Radio offers free service and an upgrade for $36 per YEAR, not per month, that will run without ads and has other perks. I like using this website because I can sign-in from any computer and all the music I like is right there.
