May is here, which means summer is knocking on our door step! We also have a whole slew of good music in the PopCrush Top 40 Pop Songs for May 2013 to provide a sountrack to our spring.

Macklemore & Ryan Lewis are seriously the feel-good success story of the year. When Macklemore isn't being an all-around good person, he and his producer Ryan Lewis sit atop our Top 40 Pop Songs with their newest single 'Can't Hold Us' featuring Ray Dalton. Their break-through hit 'Thrift Shop' also appears on the list at No. 10.

2013 might very well be remembered as the Year of Justin Timberlake, which is why he comes in at No. 2 on our Top 40 Pop Songs list for the month with 'Mirrors,' a track that is shaping up to be the hit of the summer. His smash 'Suit & Tie,' featuring buddy Jay-Z also comes in on the list at No. 8.

We think Icona Pop's 'I Love It' is such an infectious tune and we're sure we haven't heard the last of this track, which is why we included it at No. 9. And what would a Top 40 be without an offering from the most viral of stars, Psy? His track 'Gentleman,' which appears at No. 5, is making sure he will not be remembered as a one-hit wonder.

Check out our list below!
