Arizona DJ Guy Zapoleon played UB40's "Red Red Wine" four years after it was released as part of a feature on songs that should have been hits. Listeners started requesting the tune and within weeks it was topping the Hot 100.
When "Last Friday Night (T.G.I.F.)" climbed to #1 on the Hot 100, Katy Perry became the first woman to send five songs from one album to the top of the charts. The four previous chart-toppers from her Teenage Dream set were "California Gurls," "Teenage Dream," "Firework"; and, "E.T."
