I am somewhat of a perfectionist/completionist. I need to have album art, formatted tags, and lyrics for my music collection. Unfortunately you need an iTunes Store Account to automatically grab album art in iTunes which is not right. Corripio is an open-source app for your Mac that does all of this for you with a click of a button. You can go through your entire library and actually EMBED album art, and lyrics into the MP3 itself so if you ever decide to ditch iTunes for another media player you don’t lose all of that hard work. Now when I’m using CoverFlow, I am flipping through actual album covers, not just blank squares ;).
