Schoolboy Q must be one of the most coveted guest features in the game. If he's not, he should be, because he consistently delivers on other people's songs (see Isaiah Rashad's "Shot You Down" or 21 Savage's "Good Day"). It turns out though, he doesn't even charge for his guest verses.
This fun fact was revealed in Schoolboy Q's reply to a fan's tweet that expressed curiosity regarding how much a Q verse goes for. "I don’t," the TDE rapper answered. "I only do songs wit ppl I know." If you think back to his guest features, this statement checks out. Perhaps Q still receives royalties from the tracks, but either way, this is incredibly kind of him. The freebie might serve as consolation for the likelihood of Q washing someone on their own track.
