Why just SAY yes when you can scream it less formally? Edgier, more muscular way of suggesting you're certain of something - or just really like Karen O. The word "Yeah" is repeated over and over against a barrage of pounding Rock/Punk/Pop electric guitars/bass and drums, appropriate for extreme sports successes/failures and surfing/beach parties, as indicated by the '60s-ish feel @:45 replete with Farfisa organ. "Don't say no" appears @:58 followed by a bed of 'no's. Then 'yeah's. Come on - it's like the seventieth zillion version of this cut - you know the drill.
