It seems strange to see the output of Mickie Most's RAK label finally being taken seriously by record labels as well as collectors, 30-plus years after the imprint established itself as the epitome of disposable pop tunes. Yet EMI's ongoing As, Bs & Rarities series offers nothing less than the same thorough treatment that any other, more hallowed, label could expect. The format is essentially the same throughout: a gathering up of every RAK single (A-sides and B-sides) released by a given band, with the remainder of the CD filled with choice outtakes and oddities – an approach that the average Mud fan will relish. This is not the first time around for the bulk of the band's As and Bs – the German Repertoire label long ago created a masterful two-CD set around the same theme. But they still missed one B-side, 1973's "Do You Love Me," which now makes its CD debut here, and besides, two CDs of Mud can be a daunting prospect for the average consumer.

As if the flood of compilations called Best of Bowie in 2002 weren't confusing enough – there was a different track listing for each territory around the world, all bearing the same name and album cover – in 2004, a double-disc version of Best of Bowie was released in U.S., which was different than the "bonus CD" edition released in North America in 2002. It's not too different – a slightly different sequencing, it's a track longer, it has a couple different songs (and there's an edition with a bonus CD containing remixes) – but even if the details are slightly different, the overall gist remains: this is an excellent double-disc overview of Bowie's '70s and '80s peak.

T. Rex were an English rock band, formed in 1967 by singer-songwriter and guitarist Marc Bolan. The band was initially called Tyrannosaurus Rex, and released four psychedelic folk albums under this name. In 1969, Bolan began to shift from the band's early acoustic sound to an electric one. The following year, he shortened their name to T. Rex. The 1970 release of the single "Ride a White Swan" marked the culmination of this development, and the group soon became a commercial success as part of the emerging glam rock scene. From 1970 until 1973, T. Rex encountered a popularity in the UK comparable to that of the Beatles, with a run of eleven singles in the UK top ten.

If Day at the Races was a sleek, streamlined album, its 1977 successor, News of the World, was its polar opposite, an explosion of styles that didn't seem to hold to any particular center. It's front-loaded with two of Queen's biggest anthems – the stomping, stadium-filling chant "We Will Rock You" and its triumphant companion, "We Are the Champions" – which are quickly followed by the ferocious "Sheer Heart Attack," a frenzied rocker that hits harder than anything on the album that shares its name (a remarkable achievement in itself). Three songs, three quick shifts in mood, but that's hardly the end of it.

The Final Countdown: The Best of Europe is a compilation album by Europe, released in 2009 by Sony Music and Camden Deluxe. This album contains some songs from their debut album and albums through 1999. This album contains 36 songs with 18 on each CD. Europe is a Swedish rock band formed in Upplands Väsby in 1979, by vocalist Joey Tempest, guitarist John Norum, bassist Peter Olsson, and drummer Tony Reno. They got a major breakthrough in Sweden in 1982 by winning the televised competition "Rock-SM" (Swedish Rock Championships): it was the first time this competition was held, and Europe became a larger success than the competition itself.

The Cosmos Rocks is the only studio album by Queen + Paul Rodgers, released on 15 September 2008. It contains 14 new tracks written by Brian May, Roger Taylor, and Paul Rodgers. This is the first studio album of new material from the two remaining members of Queen since 1995′s Made in Heaven. The album's release came 17 years after the death in 1991 of former Queen singer Freddie Mercury. "It had some great stuff on it," Taylor recalled. "I just think that Paul's more blues and soul – one of our favourite singers, ever, but, when it boils down to it, he wasn't the perfect frontman for us. I felt the album was badly promoted by EMI, who were falling to bits at the time. We were on tour in Europe, and I went into record stores and we weren't in them. And I remember being furious, thinking, 'Why did we make this fucking record?'"
