How to downgrade from iTunes 7.0 to iTunes 6.0.5

I just upgraded to iTunes 7.0, and it is horrible! If you haven't upgraded yet, don't! There are major sound quality issues. I can't do anything in iTunes while a song is playing without the sound skipping or getting distorted. After 1 day of use, I reverted back to version 6.0.5.

After uninstalling version 7.0 and reinstalling version 6.0.5, I almost had a heart attack, though. I tried restarting iTunes 6.0.5 and it told me it couldn't open the "iTunes Library.itl" file because it was created with a newer version of iTunes.

WHAT!?!? 4000 songs rated and I can't get those ratings anymore? NOOOOOOO!

After digging a little, though, I found out that iTunes saves the previous version of the iTunes Music Library before upgrading into a folder called "Documents and Settings\*username*\My Documents\My Music\iTunes\Previous iTunes Libraries". Just rename the one that is in "Documents and Settings\*username*\My Documents\My Music\iTunes\iTunes Libraby.itl" to something else, copy the old file into the "..My Music\iTunes" folder and rename it "iTunes Library.itl". That's it! iTunes 6.0.5 should work again.
