“Girl, you are my Two’s Complement, you’re always my plus one on any occaision”

Cuz if you invert the bits of of a binary number and add one you get its negative number, so your girlfried is an equal part of you

you’re probably right about that, i never thought of it that way!

There might be, but as a standard mp3 is by far the most cross compatible format on any device. Plus, if you feel like it later you can just create a program to convert all the mp3 files into other formats.
