After partying it up with superstar friends for his 27th birthday, The Weeknd links up with NAV for “Some Way,” the first single off the XO producer-turned-artist’s debut project.

Abel kicks off the track with a stinging verse that seems to address Justin Bieber, who recently called his music “wack.”

“I got some bars for a ni**a if he wanna see / Dress up your talk if a ni**a wanna talk to me / Fuck your phone calls, I don’t want apologies,” he sings.

Soon after, the Starboy references his new girl and Justin’s ex, Selena Gomez. “I think your girl, think your girl, fell in love with me,” he sings. “She say my fuck and my tongue game a remedy…I just took that chick and I know you feelin’ some way.”

Following Abel’s verse and chorus is NAV, who boasts about his own sex game. “I think the belts inside the store look better on my waist,” he sing-raps. “I think my nuts look better on her face.” Later, he adds his own reference to Bieber’s comment: “The brown boy and the Starboy on a track / Haters gonna say this shit is wack.”

Fans won’t have to wait long for NAV’s debut. “Im dropping my first project before the month is done,” he recently wrote on Instagram.
