You’ve got to give it to LFO for bringing the world “Summer Girls” in all their 1990s boy band-esque glory. The song, released in 1999 was the lead single for the group’s self-titled album and made it to No. 3 on the Billboard Hot 100 in August of that year. Its real acclaim, though, came a decade after its release, when Billboard named it No. 16 on the biggest summer songs of all time.
