As with Lil Boat, released only four months earlier, follow-up Summer Songs 2 consists almost strictly of tracks lobbed like half-baked pies at the face of a hip-hop purist.

The bulk of these rhymes, as with those of the debut, are willfully juvenile -- Lil Yachty is only 18 -- delivered with an aloof irreverence paired with lethargic, hollow rhythms.

Purpose-wise, provocation is second only to goofing off.

There's even a track titled "DipSet," after the like-named divisive crew whose Juelz Santana, compared to Yachty, is long-winded.

All of the affected carelessness seems pretty taxing.

The youngster sounds more natural, like he's actually putting forth less effort, when he projects enough to signify alertness.

In the central track, over a lumbering beat ornamented with a shrill jack-in-the-box melody, Yachty quizzically trills "Why do they hate on me?," holding the "a" in "hate" as a rascally child would scrape a fork across a bowl.

He figures he's a target because he's paid.

There might be more to it than that.

Lacking anything as memorable as the breakthrough "One Night" and "Minnesota," this mixtape succeeds only at sustaining the rapper's 2016 visibility.
