Can't Be Tamed First Week Sales

The new Miley Cyrus album Can't Be Tamed will be the Number 3 album in the USA selling 106,553 copies in the first week of release.

The Number 1 album will be Eminem - Recovery (753,870 copies) followed by Drake - Thank Me Later (156,451).

I have to think this is somewhat of a disappointment, considering Miley's last full album Breakout was #1 and sold 366,267 copies in its first week. This means Can't Be Tamed sold less than 1/3 of what Breakout sold in its first week.

Now, it's possible that digital sales aren't being counted in this. I thought most of the new charts counted digital sales but maybe this one doesn't. iTunes currently lists Can't Be Tamed as the number 1 album.

These numbers are from Hits Daily Double, which uses Mediabase tracking, so the final numbers might be slightly different from Billboard, which uses SoundScan. I know Billboard counts digital sales, so if there's any major difference between the two charts that's probably why.
