That would be absolutely fine by me as I like small fonts on everything anyway.
Assuming of course that the code isn't limiting by number of displayed records ...
One other thing with this that has always puzzled me is that the most recently played are the ones dropped to the bottom. That's not so bad for the last played as that one is in the window and you don't need to scroll to it anyway, but the second most recently played is the always scroll one. I would have thought the ones that haven't been used in 6 months would be better off down there.
