Singer's list - max size?

[songpony]

Yes, I currently sing about 850 different songs (the remaining 50 are videos, so can't be added to the list). It probably takes 30 seconds or more to come up when a song isn't playing - when one is playing, it can take more than a minute (my processor speed is pretty good - 3.6 GHz). If I don't open it right after starting a song, I've found I can't get it open and get a song selected before the singer is done, which would then cause "dead" time.
