Did The Jonas Brothers Rip Off Another Band For Their New Song?

The other day on Twitter, Portugal. The Man passive-aggressively suggested that the Jonas Brothers ripped off their song Feel It Still with their new song, Sucker. And...they DO sound a little similar -- but a complete ripoff seems a little much?

I mean, there's even a part in there that sounds like a Styx song, too -- sometimes music just sounds alike, yo.
