UniversalAlong with albums from such current stars as Maroon 5, Justin Bieber and One Direction, the top 10 on this week's Billboard 200 chart features an unexpected act: The Bee Gees.  The group's 2004 compilation Number Ones has re-entered the chart at #5.

What's the explanation?  Credit Amazon.com.  The website marked down the veteran pop act's best-of collection to 99 cents from August 3 through 5, and that led to a sales increase of 3,049%, according to Nielsen SoundScan.  Even the death of Bee Gee Robin Gibb back in May didn't spur the band's back catalog to sell in those quantities.

According to Billboard, this is The Bee Gees' highest-charting album since 1980, when they topped the charts with another compilation, Greatest.  It's also their first top 10 since the soundtrack for Stayin' Alive, the Saturday Night Fever sequel, reached #6 in 1983.
