I'm glad you made this thread. I always wondered why there was no casual forum section as I imagine a lot of people would like to post appreciation and talk about how they use Musicbee.
I literally spent years looking for a great music player, at one point I was using 3 for different uses (not what I want). There were pros and cons to the others.
Foobar was great with my tags and low resource, but it had no mtp support and no album art main view - as well as requiring constant tweaking.
WMP12 had a great album view and syncing, but it consistently messed my tags and album art, a constant nightmare.
Mediamonkey was great for tags but it was ugly as sin, locked up a lot, and was really unintuitive.
Winamp had great radio support but it used up tons of resources and was a pain to tweak (which it needed).
Songbird had fantastic features, great podcast and radio uses, and was decent with tags - but my god it was a resource hog!
itunes was....just bad.
Musicbee had every single pro, as well as ton more (playing from main player, inboxing new records, tab navigation, auto-shutdown, etc). But the best thing about musicbee is that I've gone from being in love with it, to completely forgetting about it. Now I can just use my music how I want, and I never have to google solutions, tweak the preferences, or run into problems, which is the best compliment I can give it.
