The "Frozen" soundtrack may maintain its icy grip on the Billboard 200's No. 1 slot for a ninth week, so say industry forecasters.

Forecasters suggest the Disney film soundtrack could sell another 140,000 to 145,000 copies in the week ending April 6. That may be enough to block the likely highest debut: 5 Seconds of Summer's EP "She Looks So Perfect."

5 Seconds of Summer may sell around 130,000 to 140,000 copies of its EP, which should secure it at least a No. 2 arrival on the Billboard 200.

The top 10 of the new Billboard 200 chart will be revealed on Wednesday, April 9.

Since Nielsen SoundScan's point-of-sale data began powering the Billboard 200 chart in May of 1991, only 12 albums have spent at least nine weeks at No. 1.

Other possible high entries on the new Billboard 200 chart may include: Christina Perri's "Head Or Heart" (40,000 or so), Chevelle's "La Gargola" (40,000) and country duo Dan + Shay's debut album "Where It All Began" (30,000).

On SoundScan's Building chart (below), 5 Seconds of Summer is No. 1, followed by "Frozen" at No. 2. The Building tally is a precursor to the final Billboard 200 ranking -- reflecting the first four days (Monday through Thursday) of SoundScan's tracking week as reported by six major merchants.

Perri and Chevelle are Nos. 3 and 4, respectively, while Dan + Shay round out the top five. Shakira's self-titled album is No. 6, Nickel Creek's new "A Dotted Line" is No. 7 and Johnny Cash's "Out Among the Stars" is No. 8. (Nickel Creek's new effort may not finish in the Billboard 200's top 10, but could sell around 20,000 for the week.)

Pharrell Williams' "G I R L" is No. 9, and Manchester Orchestra's new "Cope" closes out the top 10 at No. 10. Like Nickel Creek's album, Manchester Orchestra's set might miss the top 10, as it might sell 18,000 to 20,000.
