I don't understand what is lastfm? It's like Spotify?
No. You install the Scrobbler and everything you listen to is added to your account. You can keep track of how many songs you listen, the time, the artist etc. You can use the Scrobber with almost any music player: iTunes, Spotify, Windows Media Player etc.
