Producer: Timbaland, Justin Timberlake, Nate "Danja" Hills
Album: FutureSex/Love Sounds

A booming clap and perfectly-timed synth chords makes this both one of hardest and most entertaining tracks on FutureSex/LoveSounds. The record's about "wanting to fall in love with a lusty seasonal love." We've all been there. "Summer Love" was well-received, hitting No. 1 on the Billboard Pop Songs chart and No. 6 on its Hot 100 list. Considering the way this one earworms its way into your consciousness, that's no surprise. —Tannis Spencer
