From ask Billboard.
There are only nine albums that I could find that have topped both charts for a combined total of more than 30 weeks. (There are soundtracks with greater runs atop the Billboard 200 - i.e., "West Side Story" (54 weeks) - but failed to generate a Hot 100 leader):
47 total weeks

Yet another great angle that illustrates the stronghold that "21" has had on consumers and radio in its year-plus of release. This stat further shows that the set is clearly among the most dominant in the more than 53 years that the Billboard 200 and Hot 100 have co-existed.
On the list above, look for "21" to move out of a tie with Usher's "Confessions" this week, as it's likely to notch a 24th week atop the Billboard 200, fending off Bruce Springsteen's arrival with "Wrecking Ball."
The last statement above is this one guys opinion, but I really hope he's right.
