While playing MP3s or OGGs automatically is nigh impossible, unless you do something evil like cover the screen while the music's not playing so any click starts it (which would be a rule violation as far as I'm aware), this one might catch the attention of a viewer and cause them to play it out of curiosity.
I recommend using internet radio stations for this one – currently, it's loaded with lainon.life's audio stream, but there's ones out there for stuff like vaporwave and such, so finding one playing whatever you like shouldn't be too much trouble.
Failing that though, you can just upload an mp3 or ogg to a filehost and have it play as a loop once someone clicks.
