Possibly Cheval by Igorrr

Probably Bodies by Car Seat Headrest.

But I normally think in terms of albums so probably that whole album.

You only get what you give by the New Radicals.

I would agree it changes. Best I Am by Flaw is probably the most consistent one for me.

Vampire - Lazyboy Empire

Something about this makes it endlessly repeatable to me. Also a few songs from suicide sheep and similar artists. Faded was actually in this list for a long time.

Changes often. Currently it’s The Loxian Gate by Enya. It’s in a language called Loxian that her songwriter made up. They are the only two people in the world who speak/understand it. It sounds like Gaelic though.
