I'm curious how much rock/punk flavor the soundtrack will have.
I think there'll be some, even the argument of "it's the future, 2077 you know?" is wrong if you look at how "rock" music age well.
You can listen to Ac Dc or Motorhead (Ace of spades!! lml) It sound good even in 2013 but they're something like 30years old, if not more, it's timeless.
They're classics just like Mozart, Beethoven, Michael Jackson, etc.... those kind of music don't get old (liking it or not, it's a matter of taste).
Rock/Punk/Metal, they all use "natural" instruments, using distortion, overdrive, compression yes, but the sound will never really change, a guitar is a guitar, a bass is a bass, a drum is a drum, sure you can plug your guitar, change the effects, givin it almost everysound you want, but in the end it always sounds like a guitar, in 1970, 2020, 2077, Punk / Rock / Metal will always "sound" the same, sure they'll probably play something different from now (just like the evolution from Punk-rock > Punk Hardcore > D-Beat > Grindcore, but the musical roots are the same, they just add other genre's playing style into the mix)
Look at Blood Duster, they mixed Rock'n Roll and Grindcore together, and that kick ass, could have been 50yo in the past or the future, the music is good and would still be.
In 2013 a lot of people still love and listens to The Beatles, Elvis Presley, it would be stupid to think that everyone will listen to electronic music in 60 years
Talking about Electronic music, honnestly it's the one who age the worst.
Sure there's a lot of good Album / Electronics musicians, but the "overall" sound can go from "wow! coool" to "Ewww cheesy!!!" in a few years
There was a time, the midi-sounding Kraftwerk or Tangerine Dreams were awesome, now it sound awfully old (even if the music in itself is cool, it sounds old nonetheless)
Or look at the Dubstep frenzy with the "bwoop bwopp bwiip bwipp bwobwobowbowobwo", there were a lot in the Total Recall Remake, but maybe in 20yr, everyone will laught at the dubstep as they laught at Eurodance now:
Remember, it was "soooo cool" listening to this back then... so it's hard to know what people will listen too in the future.
They'll probably listen to some "newer music" who sound like the old one, just like now, there were disco, rock, etc... and it turns in circle, now it's disco "hype", tomorrow it'll be the "rock hype", then the "old eletro hype" etc...
Look at the last Daft Punk album, it's just Disco, could have been released in 1973.
I think CDPR should just choose "good music" whenever time it's from, and whatever the genre is electronic as rock or whatever, all it matter is that it fit with the environement, it would feel more acurate to have this (or an another style's counterpart) blasting throught the speakers:

As you enter a strip club, with classy dark-red neon around, some corpo talking at a table, drunked guy trying to fondle the dancer, a few people walking around the room, conversation's sound in the background with a cigarette's smoke cloud to give a "louder" atmosphere, than hearing some "hardcore-techno-break-your-walls-your-neighbors-are-gonna-call-the-cop."
Sure, if it's a raver club, hardcore electronic would be welcome, the same for a Boostergang's bar, it would feel awkward to hear some Lady Gaga while all you see is a bunch of weird guys, wearing big guns, mohawk, leather, spikes, with dried blood on their shoes lol, some badass music would fit better, more "cinematic", just to give an example.
Anyway, if there's a band who needs to be in cyberpunk 2077 it's KMFDM, in my opinion, they sound "cyberpunk".
