Logic had his biggest year yet in 2017.

Everybody entered the Billboard 200 at number one, was certified gold within a month, and its "1-800-273-8255" went Top Five pop and led to the rapper's first Grammy nominations.

On the heels of those triumphs, Logic issued the commercial mixtape Bobby Tarantino II the following March -- just before Everybody went platinum -- and in six months struck again with the concluding fourth volume of his Young Sinatra series.

Whereas the first three Sinatra releases were tapes, this one is designated an album, coincidentally the rapper's fourth.

YSIV ties up the series with Logic sounding busier than ever.

That goes for his rapid-fire flow as much as his lack of free time, utilized and referenced early in "Everybody Dies," where he asserts his evident all-purpose approach with "I do it for the boom-bap, the trap, and the radio," and brags about having five albums and a book in the chamber.

At the same time, he acknowledges the "catastrophe"-to-"masterpiece" transition of his life from his humble beginning to stardom.

His hard-fought ascent and dream fulfillment inform much more than that track, most poignant when he zeroes in on his absent-turned-nagging father and vows to break the cycle by being an engaged provider for his future children.

Just as much emotion is felt in "Legacy," in which he portrays the father, child, and mother of a broken family, and in "Street Dreams II," an action-packed adventure that owes more to Kool G Rap than to Nas -- albeit with a twist, and with undervalued producer 6ix as his sidekick.

What comes through most is Logic's self-acknowledged eminence, an abundance of lyrical and sonic references to what he calls "real rap," and an insatiable eagerness.

(This is an album that features the entire Wu-Tang Clan on one track and a public appeal for a Jay-Z collaboration on another.) Listening to Logic can feel like waking up on a Saturday morning and scrolling through a social media feed dominated by one friend who has posts time-stamped between 6:00 and 10:00 from the gym, grocer, park, brunch spot, and bakery (including a gratuitous if eloquent focaccia dis).

To paraphrase Thundercat, Logic is out here probably doing the most.

In a way, with all its emphasis on over-achievement and a continuous supply of re-recounted autobiographical content, YSIV can be as mind-numbing as the mumble rap Logic rails against, but the proficiency and fervor are indisputable.
