Here's a mix of 2008 songs, with none of the selections pulled from the accompanying Top 10 album list. It's programmed to fit on one CD, because without a time constraint, I would have put 50 songs on it, instead of 20. Everything is available on iTunes, except the Ida Maria song, which is easily found if you let Google be your guide. There's also a playlist up at

.

"Paper Planes,"

M.I.A.

Sri Lankan star vehicle, produced by Philadelphia DJ Diplo. Though it came out in 2007, it blew up this year thanks to the Pineapple Express trailer and T.I., Jay-Z, Kanye and Lil Wayne sampling it in "Swagger Like Us."

5.

"Can't Believe It,"

T-Pain, featuring Lil Wayne

. Even more than Wayne, the producer, "sanga" and Auto-Tune pied piper Faheed Rasheed Najm was the most influential man in pop this year.

6.

"Amazing,"

Kanye West, featuring Young Jeezy

. The full-length Auto-Tuned Kanye on 808s & Heartbreak is hard to take, but this ominous march is aptly titled.

"Love Story,"

Taylor Swift

. Teen country queen pushes happy-ending-machine buttons, and we are powerless to resist.

16.

"Rockferry,"

Duffy

"Little Bit,"

Lykke Li

19.

"Palmitos Park,"

El Guincho
