No, not shameless promotion, but if you picked up the latest MacHeist you got CoverScout, and you might be a bit of a dummy (like me) and need a good tutorial on how to Tidy Up Your Album Artwork. Like that by default it only looks in your ~/Music directory instead of where your music might actually be stored (like say, having it on a NAS drive, like me). I thought it was working way too fast...
Good stuff on the AppStorm website for putting up the tutorial. Now to wait for 33,000+ songs to get indexed.
