Why aren't eminem songs on the now albums?

He was on hiatus from the years 2005 - 2007.

He's already said, he'll be releasing his sixth studio album, though the date is unconfirmed.

Rumours are that the album's to be titled King Mathers, and that it's to be released in the fourth quarter of this year (2008).

Meanwhile, just wait for more from Eminem (:
