I don't care enough to argue about it, but I don't think Kendrick had a "roll out".
I mean, by the definitions in this thread literally anything is a roll out. Generally speaking a roll out = info/promo for the album, and Kendrick had little to none. No title, no track list, there wasn't even a single.
I guess you could argue the anticipation and vagueness was a roll out....but by that logic Drake randomly dropping an album, the element of surprise was the roll out. Like I said, literally anything can be considered a roll out if we go down that path.
And I'm saying this as someone that didn't like the Kendrick album, at all.
