Alpha Geek: Whip your MP3 library into shape, Part II - Album art
Best way to find artist info and album art is to use Wikipedia. It's not easy or automatic in the least bit. But it will always have high quality album art, artists, and song info when other applications or sites fail to find what you need. Secondly, I would like to point out the solution offered for Mac users was lame. If you don't know how to copy and paste album art into your songs ..... If you want an easy way of converting ID3 tags, use iEatBrainz. Also, another helpful way of adding music to songs and albums is using a widget for OS X Tiger called: Album Art. If you want an easy way to find CoverArt when you are done converting those tags, then download CoverScout.
