Did you win a free song through the Pepsi-Apple iTunes giveaway, but then find yourself overwhelmed by the 500,000-song selection? Let Jeff tell you what songs to buy!

1. Suite for 20 G by James Taylor. Feeling down in the dumps because of winter? Tired of shoveling snow and doing fishtails in your car? Download this song and reminisce about warmer weather.
2. Help Me Scrape The Mucus Off My Brain by Ween. This is perhaps the finest hangover song ever written.
3. Rhythm Bandits by Junior Senior. Not the first song to mix surf rock with electronica, but it's definitely the most fun.
4. Grazing In The Grass by The Friends of Distinction. Baby, can you dig it?
5. Battle Hymn of the Republic by Gene Harris. A gospel update of an American classic -- it's got a jazzy feel, yet it conveys the appropriate respect.
