EMI will celebrate the 25th U.K. anniversary of the "Now That's What I Call Music" compilation series with the release of a special edition, triple-CD set.

"Now 25 Years" (EMI TV), will be released Oct. 27 in the U.K., will include hits from the 80s up until the present day, with artists ranging from rock stalwarts Queen and U2 through to current chart sensations Katy Perry and Duffy.

The "Now" series is a joint venture between EMI and Universal Music. Since its launch in 1983, the series has amassed over 75 million album sales worldwide, according to EMI, with spin-off versions taking sales to over 100 million worldwide.

The latest volume, "Now That's What I Call Music! 70," released in July, broke the record for the highest weekly sale by a various artists compilation in U.K. chart history (Billboard, Aug. 30).

From Sept. 30, iTunes U.K. will also sell a collection of "Now"-branded 20-track digital albums that cover each year from 1980-1999. Featured artists will include Diana Ross, the Police, Tina Turner, Spice Girls and Boyzone.
