4. Heart, "Barracuda": According to VH1 Classic's Behind the Music Remastered, when Heart released the band's 1976 debut, Dreamboat Annie, their record company, Mushroom Records, decided to take out a tabloid-style full-page ad with the caption "It was only our first time" along with a picture of the Wilson sisters naked from the shoulders up.
The ad implied that the Wilson sisters were lesbian sister/lovers. The band was unaware that the record company did this until they opened an issue of Rolling Stone. When they saw it, they were pissed.
This publicity stunt led to the band attempting to leave Mushroom Records. The record label rush-released their unfinished album, 1977's Magazine, and even threatened legal action. However, the ad once again got Ann really mad one night when a record exec came up to Ann and asked her how "her lover" was doing, referring to Nancy.
Ann was dating manager Mike Fisher at the time, and after she realized what exactly he was referring to, she got extremely angry and went back to her hotel. That night, Ann wrote what would become the biggest hit of Heart's career thus far, "Barracuda," about the incident.
3. Justin Timberlake, "Cry Me a River": Once upon a time, back in the late '90s, singer-turned-actor Justin Timberlake dated pop star Britney Spears, but the relationship ended in 2001. This song, which appeared on Timberlake's 2002 solo debut Justified, has been speculated to be about Spears, but nobody knows for sure.
