What movie soundtrack made you a lifelong fan of the artist/band?

When I saw City of Angels in high school it instantly made me a huge fan of the Goo Goo Dolls and Sarah McLachlan, both of whom I had never heard of before, strangely. And although I'd already heard of Paramore, watching Twilight and hearing Decode made me love them to this day. What movie songs did the same for you?
