On the computer, I use a program called Mp3Tag to manage my id3 tags. Some of these folks might have other solutions, but this has always worked for me with all of my devices. When I get an album, its first stop isn't Winamp, but Mp3Tag, I clean everything up, put an album cover in, clear the comments (LOL Mp3 id3 tag comment spam) and generally make sure everything is correct. I just did that because I'm partially OCD (an older co-worker of mine says it's because I'm part German, and Germans tend to be perfectionists) but I'm thankful for the extra effort now that I have a phone that renders the album art so nicely.
