US rapper Lil’ Wayne’s new album ‘Tha Charter III’ is on course to sell a million copies in one week in America.

By the close of sales on Friday (June 12th), the album had sold 630,000 copies.

That figure is expected to rise to the one million mark by the end of Sunday, when US chart tracking officially closes.

As previously reported, ‘Tha Charter III’ sold 423,000 copies on its opening day of release on Tuesday (June 10th).

The most recent album to come close to the magic million was ‘Graduation’ by Kanye West, which eventually sold 975,000 copies in its first week.

The last album to achieve the feat was 50 Cent’s 2005 album ‘The Massacre’, which sold 1.1million copies.
