“How's yer mood?”
Sometimes, not all the times, but sometimes, simple is best. If you're trying to deal with a global problem you probably shouldn't be looking at a nice simple solution. If your feelings are complex, some nuance in how you describe them will go a long way. But somethings are best done direct and in the smallest number of short words possible.
Not a song about getting ready to go out (as has been suggested a couple of times). It is what it says on the tin. It's a song about being asked how you feel when you're low.
Bonus points for recognising the cover-star.
Mood Is Low is the May 2023 single by 9 o'clock Nasty
