Like the title says: a vibe check based on your character's playlist. The songs in the playlist can be what your characters would listen to, songs that give your character's vibe, theme songs, etc.
Put names and pronouns if you want, and for the playlist, you can put the song name and artist or a link (both are fine). The amount of songs you put don't matter, though maybe keep it down to 3-5?
Make sure to vibe check someone else before putting out your own character!
