I’m still confused as to how it happened, but Mac Miller has become the sort of rapper whose stray online tracks are worth hearing. When Miller was a frat-rap commercial force, “Boo” was a thing that I’d yell at him. Now, “Boo” is a nicely mushmouthed rap ramble that Miller threw up online last night. He doesn’t say anything all that quotable on the song, but his casual free-associative flow, over a rattling beat, is an impressive thing to hear. Check it out below.

No word on a new album or mixtape yet, but Miller stays busy, so we may not wait long.
