With a refined strategy for harnessing the rise of streaming, where young listeners flock to rap, Migos is now zooming at an even higher level. With the release of its second album, “Culture,” out digitally on Friday, the trio focused its exuberant songwriting. It is choosing more airy, ornate trap beats and taming its staccato verbal onslaught to make better use of empty space, while tending to both its online and on-the-ground grass-roots boosters.

In New York this week, Takeoff, 22, the group’s most reserved member, compared the album lead-up to Christmas Eve, his sleepy eyes lighting up. “You just know that everything you asked for is going to be there up under that Christmas tree,” he said. “It’s our time now.”

Migos’s de facto leader, Quavo, 25, is its most alluring presence and a melodic songwriter. He was defiant about the group’s sometimes samey or excessive output, which has included more than a dozen free online mixtapes since 2011. “We’re doing the same thing we’ve been doing, making the same music,” he said “I feel like the world just caught up.”

The group’s business team is more realistic — and, by necessity, more strategic. “Truth be told, we did have a minor setback for a major comeback,” Kevin Lee, the Quality Control executive known as Coach K, said.

After a rocky 2015, which, amid legal issues, still included the release of five full-length Migos projects with middling effect, 2016 was about slowing down and spreading out. Though Migos released just one official mixtape last year, its members appeared as guests on an unfathomable number of tracks by other artists, pop and street, expanding their sonic palette and fans’ understanding of their individual attributes.
