"No Pressure" is actually more R&B tinged. Big Sean is lame on the track and shouts out Cookie Lyon. The song suffers a bit from no-big chorus while following a few downtempos. That being said, it's definitely better than LY and Company, imo.
"No Sense" has Bieber speaking in a mildly-syncopated verse for the chorus. It differentiates the track from the last R&B tracks, but the hip-hop is very lite in this song. While I'd prefer something more hard-hitting, I can really see it being cohesive with the other pop/R&B/dance/shuffle songs on the record. It's clear that he had a sonic vision for the album prior to recording
it's smart for him not to go too heavy on r&b since r&b and hip hop are practically dead.
Sonically his sound right now should be able to stand the test of time.
