Episode 280 theme song

[I Love Ai]

i watched episodes 279-280 (The Labyrinth's Hooligan) of Detective Conan. then at the end of episode 280 a theme song played and i liked it very much that i searched for the music for hours but i still can't find it. anyone knows what theme song played at the end of episode 280?

Hm... I'm assuming you mean the sad theme right before the ending was played. It's called "Ran no Ketsui ~ Hōsu ni Hi ga"(蘭の決意～ホースに火が) which translates to "Ran's Decision ~ Hose and Fire". It's the 34th track in the Countdown to Heaven soundtrack, and that's the movie the song made it's first appearance. The title is enough to explain which scene it was from in the movie.
