Why, when I try to play Felix Mendelssohn, does it play Vince Guaraldi's Charlie Brown Christmas album?

I think I know one possible reason. Lee Mendelson is credited as a composer. They are obviously different people…

Also, I think I found a related thread about this issue:

Is there any way to fix this?

go to the composer page for either Felix or Lee Medelson and EDIT make sure that they use the full name and then they shouldn’t get together any longer.

Either that or Linus is an investor in Roon and there’s no fix.

I figured it out. @Spencer_Bank, was on the right track. Felix Mendelssohn wrote the tune for “Hark the Herald Angels Sing”. I tried to remove him from the Metadta but it didn’t work. Any ideas?
