I have a fan theory about Music Meister:

I think he's a metahuman who tricked the DEO into thinking he was an alien so that they would arrest him and bring him to Supergirl so he could whammy her. Once he did that, he gained a psychic link with her and found out all about Barry and Team Flash. With this information, he used her breach device to go to Central City and whammy Barry. When he realised that both Kara and Barry were having relationship issues, he decided to use the musical world to teach them a lesson. To make them more comfortable with being trapped in this world, he lied and told them it was their love of musicals that made the dream world a musical, using their memories of watching musicals to convince them.

As for stealing their powers, that's either a physical extension of the psychic link or was achieved with alien technology he somehow got his hands on. Alien technology is definitely how he teleported from STAR Labs at the end of the episode.

I also think he likes being mysterious and has a god complex, leading him to tell HR that he wouldn't understand where he came from.

What do you guys think?
