Despite the wide variety of musicians at Bonnaroo this year, there was a commonality I observed at nearly every set, from Snoop Dogg to TV on the Radio to Bon Iver: the prevalence of the handclap. The crowd went wild each time the band gave them a beat they could clap along to, and the musicians seemed to appreciate the response. Why are handclaps so appealing? Maybe it's the sing-alongs we're taught as children, like "B-I-N-G-O" and of course, "If You're Happy and You Know It Clap Your Hands." Maybe it's the interactive nature of making percussion along with the band, or maybe it's the pure joy of keeping the beat. Either way, handclaps have made their way into every genre you can think of, including rap, folk, punk, indie rock, '80s pop and classic rock. Here, our favorite 13 songs with handclaps:

1. Farrah Fawcett

Farrah’s ’do made her a sex symbol, and her beloved feathers still show up in hairstyles today.

He’s certainly trying. So far this year, our buddy has released at least six great collaborative tracks, all of which are guest spots on somebody else’s records. Who says he’s self-centered? The man loves to share his gift! Act now and Kanye will perform at your wedding, bar mitzvah or funeral!

With today's release of Wilco (The Album), we celebrate not only a band, but also a rich musical tradition. No, not album-cover camels, or even rock 'n' roll groups with frontmen named Jeff. Rather, musical parentheses.

Not content with year-end lists, many music critics now offer their thoughts at the halfway point. Here are mine. For what it's worth, I think 2009 has been a fabulous musical year, with quality and innovation bursting forth in every genre. In typical fashion, my list is all over the place. That's because I like music, all kinds of music, and I see no reason to compartmentalize my listening habits.

My #1 album isn't out until August 18th. Sorry about that. It just happens to be the best album I've heard so far this year. When it comes out, you should buy it.
