As a 50th-anniversary souvenir, the Stones have assembled a three-disc, 50-track compilation that is the best and most comprehensive collection of the band's high points available. "Doom and Gloom," one of two new songs here, is the Stones at their best – nasty, funny, sexy and rocking hard. As for the rest, it's impossible to overstate the importance of these songs. The Stones' obsession with American blues and R&B ("Time Is on My Side," "Little Red Rooster") transforms into a sexually charged class critique ("19th Nervous Breakdown"). Finally, the indelible guitar statements, from "(I Can't Get No) Satisfaction" to "Start Me Up," are inextricable from the very idea of rock & roll. The third disc skims great moments like "Mixed Emotions" from the top of the band's underrated post-1989 material. Is GRRR! perfect? No. But as the band once said: You get what you need.  

Listen to 'GRRR!'

“The Pretender”

This song wasn't part of the planned track listing for 2007's Echoes, Silence, Patience & Grace, and was put together in a day. "It happened after we recorded a lot of stuff," said Dave Grohl. Yet it ended up as the album opener and the lead single. Grohl called it "a stomping Foo Fighters uptempo song with a little bit of Chuck Berry in it." The singer hinted at the lyrics' political overtones: "Everyone's been f---ed over before and I think a lot of people feel f---ed over right now and they're not getting what they were promised."
