I queued up several things from several artists.
Sometimes it was one file per artist, sometimes as many as 22.

ThreeTen took the drag of every queued item, except one. It failed to recognize any song in a 22 song album by Roy Orbison:

Roy Orbison  Pretty Woman Dream - Greatest Hits '2003  22 

I queued up everything except the Roy songs that it wouldnt' take, 15 songs in all. The first one downloaded and about a minute later I quit ThreeTen. I checked itunes. Nothing new. I checked the specified download folder. Empty. Song gone from queue on allofmp3.com.

It was under a dime for the song, but ThreeTen sent it off to the ether. I'm certainly not ready to try this on multiple tunes until it can handle one properly without losing it and costing me money.
