OK. I think that I am satisfied now. Here is the last update to TuneQuiz for a while. From the change log:

1.4 -- Added the ability to play by track title or by artist
Added help file
Fixed bug, answer button can no longer be clicked multiple times for score
Fixed bug, answer buttons can no longer be clicked prior to beginning game
Fixed bug, progress bar continued in some instances after selecting a new game
Reset random play position such that at least 15 seconds of playback are possible

TuneQuiz is where I want it to be now. Sorry for the rapid release cycle. Enjoy the game!
