When, instead of blasting pop music when driving with windows down (my ac is currently broken just because.......)
You are jamming out to Broadway CD's... Joseph and the Amazing Techinicolor Dreamcoat, and know from the sound of it, if it's the play version or movie version.

LOL. TBH, as soon as I remember to, I will be jamming to the soundtrack of Wicked. I burned a copy of it from iTunes and the CD is still in my comp.
And it's on a green CD. (okay, that was accident, I have a stack of colored ones-yellow, pink, green, and blue. I just grabbed a green one.)
