Ask your LOR before you decide that any non-Jewish music is muttar.
Music is an expression of the soul. As non-Jews are different than Jews in this regard, no matter how moral and upstanding the non-Jew may be, a soul-to-soul musical monologue by a non-Jew is inappropriate. This means that any non-Jewish music is potentially problematic.
Whether or not it can become kosher by a Jew copying the music and putting Jewish words to that, is a separate matter; even if it is okay to “make it Jewish”, this does not mean the original is also okay to listen to.
Not to mention, on a practical level, that you are biased in favor of wanting to listen to this music so you are, therefore, not the best judge of what is or is not halachicly appropriate to listen to, regardless of the above.
