The 57th annual Grammy Awards are this Sunday, Feb. 8, and the list of reasons to tune in continues to grow! The latest collaboration that has caught our attention is that of Beck and Coldplay's Chris Martin.

No official word yet as to which song Beck and Martin will perform, although Diffuser offered the safe performance bet of "Blue Moon", off Beck’s latest album, ‘Morning Phase,’ which has been nominated for Best Rock Performance and Best Rock Song. ‘Morning Phase’ is also nominated for Album of the Year.

Other expected artist collaborations for this year's Grammys include Kanye West, Rihanna and Sir Paul McCartney (which might be the most intriguing), Sam Smith teaming up with Mary J. Blige, Tony Bennett and Lady Gaga, and the ultra mash-up of Ed Sheeran, Jeff Lynne’s ELO, John Mayer, Herbie Hancock and DJ Questlove.

Tune in to CBS this Sunday, February 8.
