Recently I've stumbled upon a cool website, Last.fm, where you can listen online to your favourite songs. The great thing is that Last.fm is able to propose other songs that you probably like. In fact, the website keeps track of the songs you listened and then it proposes some others that are similar. All that is for FREE and it works pretty well. There is also a cool Firefox extension, called Fire.fm, that allows you to play the songs directly from your status bar or toolbar. All in all, it represents a nice way to listen to your favourite music.
