George bush made every rapper rename their album

Everything at the end of the 90s had something to do with the new millennium

You had to be there

Because Suge Knight had an album titled “Chronic 2000” which came out in either 98 or 99 so Dre couldn’t use that title anymore & so Dre ended up one upping that & released the Legendary “Chronic 2001” back in 99.

Why childish gambino got a song called 3005 lol

Because it was ahead of its time!

Back before the year 2000, calling something “2000” sounded futuristic, there was a trend of products being named “<product name> 2000” the same way they sometimes now are called “<product name> 3000”. 2001 was also the name of a popular science fiction movie and novel, adding to its appeal. Using 2001 sounded like science fiction because the idea of the third millennium still seemed futuristic even back then, only a year away from it.

9/11

It doesn't matter. Go back to sleep.

Because it was ahead of its time.
