DoDo has a point that music has a different sound across languages. Fun things happen, though, when you bring the intonations of one language to another (like in Nico's singing).

Some music has lent itself better to borrowing. New wave was also quite cool in French, and in German.

To mix up as much as possible, here's a rendering of a Neue Welle song by a French bossa nova-ish covers band:

Nouvelle Vague - Eisbaer (03:52)
