it probably has got worse, so has [imo] a lot of music, just look at the charts and you'll see the problem. plus its a lot easier these days to mix a couple of tracks on your ipad, upload them and have it somehow go viral and make you famous for 5 minutes, you don't need the dedication of days gone by.
there's still some good tunes, although often its too easily lost in the background/generic and distracting. the sea shanties in ac4 were pretty funny though, and the songs in skyrim are pretty good [or at least there are some epic covers out there] and dirt 3 has the decency to put in some well themed music, and i cant hate anything with rise against in the soundtrack.
