Just posted today at Lifehacker; something that I think all of us want to do with our music – fix the metadata so we’ll never ever have to worry about not being able to make a playlist by album, genre, artist, even year again. You’ll never have to worry about jacked up metadata again:

Your digital music library is huge. Even if you only have an iPod nano’s worth of songs, that’s still a good thousand tracks—and some of you likely have closer to four or five thousand (or more). Today’s media players—whether on your desktop or portable device—rely on metadata to organize and display all this music. If your metadata is disorganized, so’s your music player. Unless you just started building your library, or have been ultra organized from the get-go, you probably have plenty of problems with your tags—missing tags, disorganized iterations of the same artist (The Beatles; The Beetles; Beatles, The), and even some albums that have no information whatsoever. Everyone’s problems are a bit different, but here’s a systematic approach to getting your library into shape, from start to finish.

It’s all about making sure your tags are as up to date and finely tuned as possible, and this guide will help you do it:
