Now that I've been playing with it for a bit, here's a couple observations.

On custominfo, that large lyrics seem to have the bottom half cropped off. Maybe it's because I need to specify a height? I didn't see specs in the readme for what the options to a "lyrics" line are so I'm going by observation.

Using this custominfo is interesting and produces some odd behavior, but then it's an odd config so I say the bug is that I shouldn't try to do this:

custominfo1=lyrics lyrics large 0 3
custominfo1=lyrics lyrics medium 16 3
custominfo1=lyrics lyrics small 26 -1

The readme lists this twice:

-s n --space=n Set the number of pixels the program tries to

put in-between lines of lyrics in horizontal mode
Defaults to 30 pixels

I'm interested to see what types of custominfo settings people come up with.
