Featuring lots of guitar and Lars Ulrich’s son.

“Variety” doesn’t even begin to describe this week’s countdown.

In which the “loser” wins.

One of the most danceable countdowns yet is led by a group from Montreal.

Pixies are back! Sleigh Bells are back! New Ryan Adams!

Summer may be ending, but these MP3s keep our hopes alive for Fall.

Can’t beat Miguel and Monáe.

So solid Em, Katy Perry, and R. Kelly aren’t even in the Top 5.

A week of big names and bigger songs.

A countdown rich with discovery and rediscovery.

Dance, laugh, shed a tear.

A little Timberlake goes a long way.
