We’ve just wrapped up “Let There Be Rock,” where we did five decades in five days of the hottest rock songs on the planet. Every day, we counted down the top 100 tracks from the ’70s, ’80s, ’90s, 2000s, and 2010s through to now. We’ve came up with these 100 songs based on your votes for the Rock 2000, local and international radio airplay, single sales, streaming numbers and fan favourites. Here’s the Top 20 from each decade!
