I've decided to write about these when they happen. Maybe they're not as random as I think they are.
Here's the first one:
"Give You Nothing" - Bad Religion
This is one of my favorites, although I'm not sure if I've heard it recently.
I woke up with the following lyric and band accompaniment clearly in my head:
"Respectable, despicable, it seems all the same
Now we realize that we have nothing to say." - (full lyrics)
