Nothing says summer like the Beach Boys! Billboard put together this list of the top 30 summer-themed songs of all time. They checked their entire archives to see which songs—explicitly about summer—were the most popular sunshine soundtracks since the ‘50s. Based on the number of weeks a song stayed at number one, the list features favorites like, Bananarama’s “Cruel Summer,” and LFO’s, “Summer Girls.” While the Beach Boys definitely appear on the list more than once, the number one song actually came out of one of the most unlikely collaborations: Katy Perry and Snoop Dogg’s, “California Girls.”
