Random Song Problems.

For the past two months, my iTunes is showing the CD playlists out of order when I put in a disc to upload or play music. How do I fix this?

Chances are that what's happened is that you've accidentally set iTunes to sort by a different criteria. It's easy to do.

Open a playlist and have a look at the headings (Name, Artist, Album etc). If anything other than the "track number" (represented in iTunes 10 by an up arrow at the far left of the listings) is highlighted, there's your issue.
