Do you ever find yourself listening to one band for a while, not listening to them for months or even years, and then rediscovering them? This happens to me all the time. it even happens to me with books, movies and video games.
One of the oddest experiences is when I play one song on my guitar or piano and then start playing a riff or start singing words to a different song; one I wrote years ago and stopped playing because it was juvenile and not worth keeping in my repertoire. Suddenly it is new again. Having forgotten half the words, I am forced to rewrite them. That is OK by me seeing as how I judged them unworthy of perpetuation in the first place.
That did not happen to me recently. I had a similar, although completely new, experience.
