It depends on each category - but each category has a different nomination date meaning that some categories allow nominations dating back 1 - 2 years prior.
There was a lot of confusion around this back in 2016 I think it was when Taylor swift won a Grammy for an album she released in 2013/2014.
Each category has different rules. Some only allow nominations from October - October of the prior year while some allow multiple years.
Congratulations Skrill, I knew you'd make it ๐ค๐ฝ๐
Amazing guy, no matter how successful, he still remains humble ๐ฅฐ Beautiful human being/alien ๐
Back in the MySpace days, I was 13 y/o and had reasonable success with music production. Skrillex (then under the Sonny page) messaged me and told me to never stop. 15+ years later and I still havenโt. I appreciate this man ๐๐ป
