Sorry if this has already been covered but I'm confused. I love the HD3 but was dissapointed with the way it handles some things. I like to add tracks to albums such as altenate versions or other tracks from singles. SonicStage (2.3) handles this fine for me but the HD3 only puts changed albums into Groups. I can live with that and decided to just use Groups to choose what I listen to. The list is getting a bit big though. From reading some of the threads in here I get the impression that you may be able to create more than 1 group. Is that just for music genre's or would I be able to create more groups on the HD3 to handle albums I have mucked about with?
