Posted July 18, 200718 yr A new generation Avid fans may be buying everything their favourite artist puts out, but there's more than nostalgia fuelling vintage sales. "Young fans aren't excluded from catalogue sales - especially the ones who really get interested in music. There's always that sense of discovery," says Geoff Mayfield, the director of charts at Billboard Magazine. Not everything maintains long-term success. Asia's self-titled 1982 album was the biggest seller of 1982, but only sold 5,000 copies last year. Whitney Houston's 1985 debut, also self-titled, was 1986's top album, but now sells about 7,000 discs a year. The same trajectory has befallen past mega-hits like Ace of Base's The Sign, Bobby Brown's Don't Be Cruel and the Spice Girl's Spice. Though one of the bestselling artists of all time, Mariah Carey's self-titled debut sold a measly 5,000 copies last year. The Backstreet Boys' Millennium managed only 9,000 sales. only 900 copies is not bad at at all considering the facts that its like 13 time platinum.
