Enjoyable film but misplaced title/ end credits

I really enjoyed the film. While the ending was a little bit of a let down, I thought it was well made. My main gripe about the film though is the choice of the credits. I know this seems like a silly thing to argue about but for a film set in 1849, as soon as the film cuts to black we are treated to loud music that doesn't match the film (likely a contract/ sponsorship deal between the studio and the band agents). The credits also look like they belong from the latest Tron film or Mirrors Edge video game. It takes you out of the film and is an unfortunate choice when I really liked the original soundtrack.

That said I still enjoyed the film but does anyone else feel the same?
