for me a big problem is the big difference betweens the two "generations" of the nexuiz-music, the first from elysis, the second from blkrbt.
i'll write my opinions about the tracks here:
beast of insanity: a weird track. imo a bit to monotonous and short and not fitting to nexuiz. but the original concept is good.
brainsukker: good when i got used to it.
breakdown easy: thats one of the tracks which formed my nexuiz-music style. really good.
brokenlight: also a bit monotonous after a while. those e-guitars starting in 0:43 are good, but really monotonous. but the concept is really good.
calling bogus: good.
chaos fog: really good.
desert3: i don't like that. the violins are much too high-pitched. thats not music for nexuiz.
digital pursuit: well, afaik it's not used anymore.
infight: good.
neuronal diving: really good, e.g. for space maps. it's not used often enough now

ninesix: the beginning sounds too much like rock, apart from that it's really good.
northern lights: really good.
sixtyfour: really good. the violins are a bit to monotonous at the beginning.
sixtyfour revisited: awesome. really. the beat is great, the bass is great, everythings great. i thinks this also fits to space maps because it creates a... ambient.
stairs: the e-guitar doesn't fit really. ithis track is not so good, but not bad.
subcities: really good. i once played a match in a grey city map, and i think this track was played. it sounded like this track was made only for this map.
thru the mirror: really good.
if you don't know how to access the tracks or how they are names, open /nexuiz/data/thebigpk3 with winrar (or maybe 7z)

well, now it's your turn... what do you think about the music? about blkrbt vs elysis? did i make something terribly wrong and messed everything up? is there any new music upcoming/included after 2.5.2? what do you think nexuiz music should sound like? should i STFU because i don't know anything about good music?

just write your opinions/thoughts.
