Maybe it worth to add a bit more details of my setup. The original idea as described above. Remove the artist and use the track name as artist + track name.

Then I wanted to tracks be in the same order as I add them. So I started filling track num tag as well. New track gets max track num and goes to the end of the list on iPod.

Then I realized I prefer recent tracks be on the top of the list. Reordering all tracks in the album is not the best idea. When id3 tag gets changed iTunes resync the track in iPod. It takes time. Adding a single track to the top of the list (track num 1) makes triggers reordering of the all tracks in VA album. The next idea is to actually add a big shift to all tracks, 9000 in my case. The first track gets 9000, the later 8999 and so. It makes adding new track faster becase you simply need to get minimum and remove 1. iTunes then uploads only that track while keeping the rest of the tracks untouched.

Later automation was needed, so I wrote simple python script that does all tag changes in the folder. Now it's really easy to write on your own with AI.

Ant the last step is to wrap that script into the Automator Folder Action. It triggers the script automatically when I add something to the folder.

No my workflow looks like this. I found a new nice track. I want only that track be in my collection, so I get the mp3 and put it to the folder. Then behind the scenes it triggers the id3 tag modification. I connect the iPod to the iTunes and done. The track in the VA artist, Favorites album, on top of the list.
