You know how you start listening to iTunes, putting it in the background so you don't get distracted from your work, then a new song comes on that you really like, so you go back to iTunes to rate it, then you notice the song is from a compilation and it's tagged all wrong, so you start re-tagging it, then you notice that the entire album the song came from is also tagged wrong, and the artwork is missing (or worse, it's a 50kb x 50kb square photo that you grabbed from google images when you were drunk and burping up beer and pizza fumes so toxic it nearly melted your monitor), and the albums next to it are also tagged wrong because the dillhole who uploaded it put the genre down as "Spoken Word" instead of "Rock" and embedded his stupid sig, BiGgIe B@LLz MuZiK BoY!, in the comments? Now you have no choice but to drop everything you're doing to address these crimes against your music library and once you get started, you simply can't stop, and the next thing you know, it's 5pm - time to go home! You just wasted your entire flipping day fixing your iTunes library. Again.
Well one day, my friend, you will realize that "perfecting" your iTunes library is an impossible goal -- iTunes is The Rock and You are Sisyphus. Give up. Relax. Enjoy your music again. As long as you have it tagged with album title and artist, who cares about the rest? Toss it in there and press play. Then fire up I Love Stars to rate your music without looking at iTunes and you'll never be distracted again.
Tested and working fine in Snow Leopard.
