There are also hundreds of "cover" songs on Spotify that, from what I can tell, only try to earn plays through mistaken clicks.
For a good example, search for Thrift Shop -- you might be inclined to play "Thrift Shop" by "Thrift Shop" on his hit album "Thrift Shop." It has 675k plays already.
AC/DC has an interesting twist related to cover bands -- the band only has one song (through an old soundtrack) on Spotify. About a dozen cover bands have filled the gap; the top tunes for each of them collectively have over a million listens.
I don't think it's about misclicks only. Another reason they get plays is because they automatically get queued and go on after the real deal when you search for a specific track.
