Before I report this to Mark/Space as a bug, can anyone else who listens to AAC (not iTMS) music files verify this?

If I copy a .mp3 file to my Treo/SD card from iTunes using Missing Sync, the mp3 will show up in the song list when I click Missing Sync in the Source list on the left side of iTunes. If I transfer AAC files over they do not appear in the song list. They ARE on the SD card, and I CAN play them using Kinoma just fine, but I cannot essentially view my song list or delete songs from iTunes.

I use AAC because the files sound the same as mp3, but have smaller file sizes. Kinoma Player 3 EX plays them just fine. I think even Real Player can.
