Adele, Lionel Richie & Whitney Housten most successful for 2012

We ma yonly be halfway through 2012 but the forerunners for most successful album and artists are flowing in already.

Topping the list are Adele, Lionel Rochie and Whitney Housten.

There'e are no suprises the UK songstress Adel would be included. Her album "21" has sold 3.3 million copies in the last 5 months alone. And with Whiteny Housten's untimely death earlier this year, it's again no surprise sales of her "Greatest Hits" album has soared since February.

But the inclusion of Lionel Richie may take a few by surprise. His latest release "Tuskegee" is a compilation of duets including the likes of Shania Twain, Kenny Chesney, Willie Nelson and Jimmy Buffet. The album is the on "new release" out of the three and is Richie's best selling in over 4 years.
