couple points I'd make...
1. Travis' tour is selling out arenas right now. Clearly he's popular, but the sales aren't representative of that
2. One of the better ways to determine true popularity via streaming boils down to albums with the most songs with over 500k or 1mil sales. I saw an article last week that said Cardi and Kendrick are the only recent rappers to release an album where every song has sold 1mil or more. I'd imagine Drake will join that list with Scorpion in a few months, obviously. Whereas a lot of artists are living off 1-2 hits inflating everything. I'd bet money that Lil Baby's album streams are like 90% based off Yes Indeed, for instance. Hits matter, folks...
3. Astroworld was a bad album, admit it.
