Is this related specifically to Bipolar? I know that racing thoughts are, but is making lyrics/changing words to tune something associated with it? I notice I do this as well, but to be honest I cannot think of a time when anybody else I'm around has done it. Sometimes I will use songs to sooth myself as well so I just start singing a made up song out loud if I'm feeling any sort of negative emotion.

Hmmm. O.o
