What do you mean by “HD music video”? If you mean a literal video, then today’s video and audio codecs are more efficient than what Flash used, not less. If the music videos were that small then they must have given up a lot in quality. If you mean a Flash vector animation, then that’s different of course, but that doesn’t describe a typical music video.

Conventional video codecs are also pretty good at compressing animations. I once made a multi-minute animation of a plane taking off and H.264 compresses it to hundreds of kilobytes.
