From the dev: "TotalTunes Control is no longer developed. Please think twice before buying it !"

From what I understood, it's lack of time to keep TotalTunes Control competitive against Coverstream and the likes that made him stop (he's a student).

For me it works perfectly.

@deef : 10% on what machine + OS?

I switched to CoverSutra a few versions back when the MacHeist came out -- see comments there -- this program was using 10%+ of CPU when idling, comparing to <1% for CoverSutra.

Don't upgrade to 2.2.3 It's now shareware :( Time to look for a free alternative or go back to using my CoverSutra

This has changed to shareware ($8). I didn't appreciate that the last update started demanding money without giving an option to stick with the last free version.

TotalTunes Control phones home with update checking turned off. No thanks.

it has a search feature in Leopard but there doesn't seem to be any way to act on the results ....they're listed but you can't play them :(

It only seems to show the artwork about 2/3 of the time, even in files where the artwork is in the file. I haven't spotted a pattern but I'm guessing that it only shows artwork in iTunes database of artwork, not when it's embedded in the mp3 file. Not so nice if much of your collection consists of recordings that aren't on iTunes.
