Everyone you just mentioned's entire careers more or less revolved around smoking weed.
And real talk, I don't even like weed but I'd much rather hear a song about niggas getting high than one more fucking song about jewelry, cars or money.
That said, I don't know shit about this Wiz Khalifa nigga, but tht Black and Yellow song doesn't make me wanna put my head through a wall.
And that's rare these days.
