I don't use the effects in WMP at all.... But I just never got on with Winamp - just didn't "click" with it...

I am getting used to WMP11 - I found you CAN turn the auto-updating off and still be able to use the metadata services to download track data, but you have to do it manually (won't do it automatically as you play stuff like in WMP10 - but then, in WMP10 it didn't try to change stuff you already had in there)

The "add to library from specific location" is still missing which is a major fuck up IMO, as is not being able to turn off folder monitoring, and the biggest fuck up is not being able to set the player backround as black for the "now playing" part (and the lack of artist/album/track info on the now playing screen)
