For me at least it was a Wendy’s commercial briefly breaking up the band Violent Femmes. The bands original lineup consisted of Gordon Gano, Brian Ritchie, and at various points Victor DeLorenzo, and their music touched on themes of angst and sexuality. In 2007, Ritchie sued Gano for half ownership of the band’s songs, which were all credited to Gano. The impetus was Gano allowing Wendy’s to use their iconic song “Blister in the Sun” to advertise their chili. Ritchie was appalled, sued Gano, and it let to their breakup in 2009. But in 2013 the original trio would reunite at Coachella, and they’ve since continued on (albeit without DeLorenzo who only reunited with them briefly in 2013).

Edit: just so we’re clear I agree with Ritchie that he should’ve gotten more credit as a songwriter in the band and it feels out of place to use a song about wet dreams (and other things) to advertise chili.…
