The early arrival of A$AP Rocky's new album, At.Long.Last.A$AP, not only caught fans by surprise Monday night, but its impact will also be seen on the U.S. charts, as the LP is expected to debut at No. 1.

As Billboard points out, Australia-based Christian worship band Hillsong United's new album, Empires, was expected to compete for the top spot against Louisiana rapper Boosie Badazz (aka Lil Boosie), whose Touch Down 2 Cause Hell also released this week.

Both sets are expected to sell about 50,000 equivalent album units, with a quiet release week giving Empires an advantage. However, industry insiders are now predicting A.L.L.A., which was previously aiming for a June 2 release, will debut with 120,000 units and easily snatch the crown.

A$AP Rocky's 2013 debut record, Long.Live.A$AP, also started at No. 1 on the U.S. charts when it arrived.
