Batman Forever: Kiss From a Rose, Seal
The movie: Batman Forever
The song: 'Kiss From a Rose', Seal
Arguably the best thing about Batman Forever, Seal’s beautiful and lavish ballad was used over the end of Joel Schumacher’s superhero movie propelling it to the top of the charts. Various interpretations of the lyrics deduce the song to be about love, sex, drugs - and/or all three of those things.
Bonus knowledge: According to the dark recesses of the internet, Seal wrote 'Kiss From a Rose' in tribute to Crosby Stills & Nash while living in a squat in London.
