Q: I have one song in an album in my iTunes library that is out of order – it’s the third track in the album, yet it shows up as the first track. How can I fix this?
A: First, make sure the tracks are sorted in album order: click the Album header at the top of your iTunes library and make sure the triangle is pointing up. Next, select the offending track, then select File > Get Info. Click the Info tab, and check the Track Number fields on the right of this window. You can set the track number here; in this case, set it to 3 of [the number of tracks in the album]. However, you might find that other tracks are out of order as well, if they don’t have the track number tag set. In this case, go through the tracks on this album and set them all to the correct numbers.
