Scrobbing configuration

[artem-zinnatullin]

From email: "I mostly listen to Indian soundtracks which generally has one composer for the whole movie and different artists singing each track. With the existing scrobbling of "Song Artist - Track name" is kinda misleading for Indian soundtracks. I would love to have an user option which would let me scrobble "Album Artist - Track name". "
