In short, distracted by whatever the latest shiny was. So whatever profound thing I was going to say, now all I can say is that on the way home, I heard what was definitely an Offspring song--not one I recognize, and I don't think it's one I've ever heard. But knowing the singer's voice and knowing how they sound (there was a bit of a giveaway in a particular riff which was strongly reminiscent of Divide By Zero), it was definitely an Offspring song.
I'd tell you which, but...shiny struck again, as some good music by some bands I wouldn't know distracted me. (Well, the song immediately after was an AC/DC song. But the song or two after that, not so much. Good music was good music though.) Meaning I couldn't quite remember the chorus. I vaguely have the sense it's "Out of", with the singer expressing vocal distaste at the situation and being glad that it's about to be over, but I can't pin it down. Oh well.
