I was still using Sonique up until a couple of months ago when I upgraded to Win7. Tried AIMP on the new system and have made the switch to it full time. Still sticking with KMPlayer for vids. ACDSee mostly for browsing pics, sometimes FastStone. I always used to keep K-Lite Codec pack updated, for no particular reason. I've yet to get around to installing any extra codec packs on this machine (suppose I won't unless I hit snags).
