If you're picky, you'd be willing to manually do these things yourself.  Getting an automated service to do it for you suggests otherwise, as you're implicitly willing to accept inconsistent tagging styles and possibly errors from whoever submitted the tagging data.

Another reason to use MediaMonkey.

Play All with MediaMonkey > Select All > Right Click > AutoTag from Web > Select Titles, Track #s, Cover, Album Name > OK.

If you want your Filenames compliant as well Select All > Right Click > Auto-Organize Files > Select Tag formation. (I prefer Track# - Artist - Trackname)
