Lovefool by the Cardigans was a single from their record release First Band on the Moon in 1996. The single would gain notoriety when it was featured in Baz Luhrmann’s Romeo +Juliet.
Per Songfacts, the song topped the Billboard Hot 100 Airplay and Top 40 Mainstream, but was kept from the Hot 100 because it was not issued as a commercial single (until December 1998, songs were not eligible to chart on the Hot 100 until they released a single in the US).
This song was super popular back during my time in high school and was played heavily around Valentine’s Day.
I apologize if this song gets stuck in your head.
