No, some of the music of the NES and SNES era are the best music ever written. And I was born AFTER that era, so by the childhood argument my favourite music ought to be of the early Pentium games I played... I only heard the music of the SNES era more recently. They are actually THAT GOOD.

Ditto, the thing that people still listen to Mozart and Beethoven even though they've been dead for centuries.

I'd argue that music nowadays is regressing to the lowest common denominator of rhythm and losing all the melodic complexity I like. And melodic complexity is perfectly achievable using only 8-bit instruments.

On my end my visual imagery is poor, I can barely remember faces, places clearly, but it does exist somewhat.

HOWEVER

My aural imagery is nearly peerless relative to any of the people I know in real life, I can sing songs in languages I know after two passes and in languages I don't after about 10 passes, I can isolate specific instruments from my memory of a song and play them back, not just the melody; I remember music not just as a whole, but as coordinations of multiple single instruments.

The idea that aural and visual imagery must be closely linked in itself is a generalisation.

Heck, for an extreme example I'd bet that the blind from birth generally don't have visual imagery and have greatly above par aural imagery, whereas the deaf from birth generally don't have aural imagery and have greatly above par visual imagery, though there will be instances where they have neither.
