The latest edition of MuchMusic's popular compilation "Big Shiny Tunes" seems to have lost its lustre, and all signs point towards the "Eminem" factor.

"Big Shiny Tunes 7" entered the charts in second on sales of 25,100, however, it was a far cry from last year's edition which debuted at No. 1 on sales of 68,500.

Meanwhile, it didn't take long for Eminem to climb back on top of the Canadian album charts. The soundtrack to his film "8 Mile," anchored by his hit single "Lose Yourself," found itself back at No. 1 this week on sales of 37,700, according to data compiled by Nielsen SoundScan Canada.

The album knocked U2's compilation "Best Of 1990 - 2000" down to third and once again gave Slim Shady two albums in the top 10 -- his previously released "The Eminem Show" (10,100) placed 10th.

Of note, U2's greatest hits package sank dramatically this week with sales of just 22,100, compared to the 55,900 it rang up last week in attaining the No. 1 spot.

Pearl Jam's new album "Riot Act" (20,000) debuted in fourth, the french compilation "Mixmania" (16,900) fell one position to fifth, Avril Lavigne's "Let Go" (14,400) remained in sixth, while Elvis Presley's "Elvis: 30 No. 1 Hits" (11,300) dropped two spots to seventh.

New York rapper Jay-Z made his mark on the charts, debuting in eighth with his latest album "Blueprint 2: The Gift & The Curse" (11,100), and french artist Francois Perusse's "L'Album Pirate" (10,900) entered the charts in ninth.

Notable chart movement included Justin Timberlake's solo debut "Justified" spiralled to 14th from third and Christina Aguilera's "Stripped" fell from eighth to 15th.

In other chart debuts, Missy Elliott's "Under Construction at No. 24, 3 Doors Down's "Away From The Sun" at No. 25, Phil Collins's "Testify" at No. 27, TLC's "3D" at No. 31, and O-Town's "O2" at No. 38.

In the U.S., Jay-Z debuted at No. 1 on sales of 545,100, "8 Mile" (400,200) slipped to second, Missy Elliott (258,800) entered in third, Justin Timberlake's "Justified" (188,600) dropped from second to fourth, and Pearl Jam (165,900) debuted in fifth.
