"Every year we look back at all the new music played on Radio 2. We make a list, we check it twice, then we crunch some numbers to find out which songs were at the top of their game in 2016. For you math lovers out there, the songs were ranked based on national airplay, digital sales and their peak chart positon on the Radio 2 Top 20.
Listen to the full countdown on CBC Radio 2 on Monday, Dec. 26 (and again on Monday, Jan. 2) on Radio 2 Morning with Raina Douris at 6 a.m. (6:30 a.m. NT) and Drive with Rich Terfry at 3:30 pm (4 p.m. NT)." ( from CBCMusic.ca )
