That's quite the loaded question. There are tons of variables that determine which lenses work for which projects.. if you're just starting out and want to learn, I'd recommend a Nikon to Ef adapter and some older Nikon f mount lenses like the 50mm 1.4 or the 35mm 2.0 but those wont give you the "anamorphic" look. To get that, go buy an anamorphic lens or adapter. Those can get pretty pricey pretty quick.
More specific recommendations will require more specific information on your part: what kind of music video, what kind of look are you going for, are you shooting mostly wide, telephoto, with primes, zooms, do you want flares or a clean image, etc.
