A very interesting music discovery service, Like.fm can look at these songs that you have played and tell your friends which music you like. As its stands right now, Like.fm can look both at the tunes you play on your desktop, and the ones you play on your browser in order to come up with a list of favorites to be shared with your friends.
That is really neat, and Like.fm also scores points when it comes to its actual implementation, as you can authenticate who you are via Facebook, and instantly begin following all your friends there who also happen to use the app.
The list with your favorite songs will be assembled without you needing to input anything. You will go about things the usual way, and the list will be compiled in real time.
In any case, it must be pointed out that you can delete items manually from your list before it is spread around. So, the ones among us who like to sample new artists via YouTube have no reasons to worry about songs by teen sensations and the like plaguing our lists just because we gave them a try just that once.
