Recently I found a website called Songza.com The website is very interesting for all music lovers who want to listen music online for free. In this site you can find all most all sort of music. May be that’s why their tagline says it’s a music search engine and an internet jukebox. You don’t need any player to play songs from this site because the song is going to play right in your browser. Some special features of Songza are

• Your own playlist
• Link to song
• Can embed to your site
• Send to a Friend
• Rate the song
• Watch video of that song

You can even promote your own Band through Songza. Here is the link Self-Promotion Beta Program. I am not sure about sound quality because their source for playing song is Youtube.
