なお、実際には椅子の軋む音らしい

The first thing you need to know about this sound effect: It might not be a mattress, or even a sample. The commonly cited ground zero for salacious squeaking in hip-hop is Trillville’s “Some Cut,” a 2004 crunk landmark produced by Lil Jon. “We were in the studio, I was making a beat with my boy Craig Love, who plays guitar, and Le Marquis Jefferson, who plays bass,” Jon remembers. “I’m rocking back and forth in the chair as I’m making the beat. Craig’s like, ‘you hear that?’ ‘What you talkin’ about?’ ‘The chair is squeaking on the beat.’ ‘Holy shit!’ So we mic’d up the chair, I put on headphones, rocked back and forth and we recorded that and put it into the track.”
