Yes, there seems to be a massive obvious correlation here: people who are good at learning difficult skills over time (an instrument and musicianship) are good at learning difficult skills over time (a new language). I doubt there's any real link/cross-sharing between music and language here.
Some people enjoy investing time into something that they will be bad at for a very long time and then become good at, and some people hate it. If you went through that with music as a child, you're probably more likely to have the confidence to want to go through it again as an adult with a language, because you know that it's something you've done before successfully. Programming's in the same category.
