An eclectic quartet of Canadian acts is atop the latest edition of one of Billboard's popular music charts.

Crooner Michael Bublé's album Christmas, pop sensation Justin Bieber's Under The Mistletoe, rapper Drake's Take Care and rock troupe Nickelback's Here and Now are first, third, fourth and fifth (respectively) on the Billboard 200 music chart.

Adele's album 21, which has spent the past 41 weeks on the chart, is in second place. Billboard also named the British singer-songwriter its No. 1 artist of 2011 on Friday.

The Billboard 200 tally highlights "the week's top-selling albums across all genres, ranked by sales data as compiled by Nielsen SoundScan."

Each week, Billboard publishes dozens of music charts using formulas that reflect sales, streaming and radio play. In addition to the Billboard 200, other popular charts include the Hot 100, Radio Songs, Hot Digital Songs, Digital Albums and the Social 50.

The firm also publishes international breakdowns (i.e. the Japan Hot 100, Germany Songs, Canadian Hot 100), online-focused charts (YouTube, Yahoo Video, MySpace Songs) and genre-specific album and song charts (e.g. Pop, Rock, Jazz, Tropical, Gospel, Holiday).
