Top ten: Teenage kicks

1. Taylor Swift, "Fifteen": Such a perfect description of what freshman year at high school is like (or at least can be like) that only someone young enough that their memories aren't yet tainted by nostalgia or cynicism could've written it.
   
2. Beyonce, "Single Ladies (Put a Ring Around It)": Dangerously in love.
   
3. Hercules and Love Affair, "Blind (Frankie Knuckles remix)": The proper use of Antony.
   
4. Franco, "Marie naboyi": Each disjoint section would be a career highlight for lesser lights.
   
5. Verckys, "Marcello Tozongana": Saxman Verckys here sounds like he belongs in the Congolese pantheon.
   
6. Franco, "Lisolo ya Adamo na Nzambe": God and Adam argue, guitar plays peacemaker.
   
7. Taylor Swift, "The Best Day": Gooey, but damn, does she understand structure.
   
8. Katy Perry, "Hot N Cold": I don't usually have a problem with opportunism: I liked the Fergie album guiltlessly. Still, the likelihood Perry will be around for ten years makes me queasy about liking this.
   
9. The Bronx, "Young Bloods": If the song doesn't give you a seizure, the video will.
   
10. Grand Kalle & l'African Jazz, "Parafifi": This was on Rumba on the River, but I didn't get into it until I heard it on The Rough Guide to Congo Gold. Either way, great groove.
