In my opinion it's the 90s and it's not even close
>Peak thrash and death metal (Megadeth, Metallica, Entombed, Carcass, Death, etc)
>Peak "electronic" music (Prodigy, Portishead, Nine Inch Nail, Massive Attack)
>Lots of different subcultures like skate punk, hardcore, grunge, no wave, shoegaze and so on
