You know when your MP3 files are a mess. You have albums by The Beatles, Beatles, and Betles, four copies of the same song in different bitrates, and your friends are boggled by the files in your collection with names like 593_afeerb.mp3 and grtst_Hits_TRACK1_.mp3. It's time to clean them up, but like the junk drawer in your kitchen, the still-packed moving boxes in your basement, or the decade's worth of old clothes in your closet, you really don't have the time. Fortunately, unlike any of those tasks, technology can lend a hand and practically do your MP3 organization for you. Here's how you can straighten out a folder with gigs worth of messy MP3 files in only an afternoon.
