"Quickly breakdown the transitions btwn an artist's discography"
For the artists who's entire catalog you're familiar with (hoping it's not TOO long)...quickly run through the transitions, changes, and evolution of the artist between their albums. You can speak on anything...the change in production/producers, guest artists, their voice/style, who they aimed to appeal to, etc. etc. etc. etc.
if somebody posts one, you can just respond to theirs and speak on how you feel, co-sign, disagree, cuss them out, however you want to do it.
