The Japanese definition for 神曲 (kamikyoku) is just "incredible song" which I think is probably the intended modern Chinese definition in these contexts (I speak both). I'm not sure if it's an example of wasei-kango [1] (Japanese-invented words being incorporated into Chinese, i.e. "phone", "bicycle", etc.), but 神曲 has been used to describe online videos of Japanese songs for at least 10 years with little descriptive meaning beyond "this is a great song" (for example, this medley of the Pokemon Mystery Dungeon soundtrack from 2007 [2]).
