I was playing normally with a friend and went out to go collect flowers for dye and when I dipped into the water I assume and swam on the surface across to the birch forest below the mountain I live on it, began playing Dragon Fish completely randomly and wouldn't stop until it played the entire song even though I wasn't underwater in any way or deep in the ocean. I also had a previous song play that was not part of the overworld land's normal soundtrack but brushed it off, this has been ever since the nether update and this has never occurred before.
