Music inspired by SPN

As the title says… We know that the song ‘Watching over me’ by Radio Company is about Dean and Castiel, but what about other bands? (Not as close connected to the series?) I recently heared the song ‘chupacabra’ by Hola Ghost, and saw the lyrics, saying: ‘Time to reach out for your Supernatural friend.’

So I’m sort of convinced that this song isbinsoirwd by the series. Are there more songs like this out there?
