It's not uncommon for musicians to blend genres. Enigma, for example, has an entire album that's basically a remix of Carmina Burana. A number of industrial musicians (Clint Mansell, Trent Reznor, Graeme Revell) branched out into scoring and musicians like Danny Elfman and Anne Dudley, stalwarts of motion picture scores, cut their teeth in new wave.
That's not what's going on here, though. Here, someone has made the decision that Kanye West is already of a par with Beethoven in an ill-conceived attempt at hipness.
