i (personally) definitely don't need more then 1. Although i like the feature, i'm not even sure if i would use it for music. The thing with music is that you listen to it, not watch it And i often turn off my TV when listening to radio/music.Is it enough for me to add support for 1 gif, or do you need more than that?
I liked visualisations in the beginning also, but noticed i hardly watch it and i prefer the NowPlaying screen with fanart (before the screensaver kicks in).
