Fire.fm

Fire.fm is an add-on for the Firefox browser that lets you listen to all your favorite songs via the Last.fm database.

You can listen to songs from your favorite artists and discover new artists with a similar style, all without leaving your Firefox browser.

With the Fire.fm controls, you can basically perform all the same actions as you can with the official Last.fm client, like marking a song as a favorite or removing songs or artists you don't like.

For all these reasons, Fire.fm is an excellent choice for music lovers and fans of Last.fm.
