right-click context menu Convert ID3 Tags... &gt; None a few times to remove all existing tags and then Convert ID3 Tags... &gt; v2.3 to build a fresh tag with the information still held in the iTunes database. I've read in the past that iTunes isn't fully compliant with the v2.4 spec. although this may no longer be the case, however support for v2.3 is widespread so I would suggest using v2.3 over v2.4. One cover for multi-disc album Multi-disc albums are often listed as Album (CD1) for CD 1, Album (CD2) for CD 2 etc. To display these properly using just one cover, each disc should have the correct Disc X of Y values set, and then the entire album should be given the single title Album . Being somewhat obsessive I also renumber the tracks sequentially, working backwards from the last track (so that no two tracks ever have the same number) until I reach disc 1. You can still give tracks from the individual discs different artwork should it be relevant so that the correct artwork will be displayed as the album progresses. I've also written a (Windows only) script called AddToTrackNumber which can help with the renumbering aspect. The script SingleFromDouble should do something similar for Mac users. Tracks out of sequence Check that all tracks have the same/correct disc no. For a single disc album this should be either blank (my preference) or 1 of 1. iTunes will sort tracks with a disc no. of 1
