As irresistibly loving as a child’s smile, “Milky Way” (streaming below) by Brooklyn’s Air Waves glints the kind of unabashed joy that seems at the root of pop music.But the warmth of this lead single off the Nicole Schneit-founded band’s forthcoming album ‘Parting Glances’ belies deeper consideration. “Hold me,/Don’t let me go,/Can anyone settle?” Schneit sings over gentle guitars and steady drums, that last word apparently referencing the difficulties of romantic commitment but perhaps hinting at the broader idea of compromise. Such is this songwriter’s intrigue; she enables various meanings on a dime. ‘Parting Glances,’ which was recorded with Woods multi-instrumentalist Jarvis Taveniere and counts among its featured artists Jana Hunter of Lower Dens, is due September 18 via Western Vinyl. You can see Air Waves live at Shea Stadium on July 15. – Zach Weg
