What time is it? Top 20 time! It's Monday, which means the team at PopCrush is serving up another list of the hottest songs in pop. As always, we've handpicked these tracks based on radio spins, chart performance and overall response from fans. This week, Maroon 5, Gym Class Heroes, Jessie J, Kelly Clarkson, Adele and Bruno Mars all make the countdown, in addition to a bunch of other great pop tunes. 

Coldplay's 'Paradise' has been knocked out of the countdown this week, making way for Maroon 5's brand-new song 'Payphone.' We wonder if this one could be as big as 'Moves Like Jagger,' which is still getting tons of spins nearly a year after its initial release. Meanwhile, Gym Class Heroes continue to hold down a spot on the countdown, making a huge jump from No. 20 to No. 13 this week. Ms. J, Clarkson, Adele and Mars are also going strong, but could Bruno's 'It Will Rain' be the next song to get knocked out, since it moved from No. 16 to No. 19? Also, indie rocker Gotye and fun. are repping their genre, with fun. coming in at No. 1 with 'We Are Young' and Gotye continuing his radio domination with 'Somebody That I Used to Know.'

Take a look at our list of the Top 20 Songs for the week of April 23-29, 2012 below, and be sure to tune in to the PopCrush Top 20 countdown (see a list of radio stations it airs on by clicking through below). Also, check out this week's About to Pop, where fans can vote on an up-and-coming track from five different artists -- the winner will get their own special little spot when the countdown broadcasts. Listeners can expect to hear Bruno Mars' 'Runaway' this coming Saturday and Sunday!
