gtcd gets extremely unresponsive if you put in a cd with say 99 tracks. A few example cd's are NIN - Broken and Marilyn Manson - Antrichrist SuperStar. ( maybe gtcd just doesnt like those bands.. ) Either way, you have to sit and wait *forever* for it to update the screen on gtcd, if you put stop/start/nexttrack etc.. it takes around 5mins to actually do that function.
I have been assured by the author that no such problem exists, and in fact have had no problems with CD's with many more than 20 tracks on them.
