Magic Kaito Special OST?

[Obelisk]

Not sure if this is the proper section for this... Although, I recently watched all of Magic Kaito (12 episodes) and Magic Kaito 1412 (24 episodes). Anyways, the original (12 episode series) had some BGMs I liked. I couldn't find any information on the wiki about this. So I just wanted to know if the BGM were exclusive to Magic Kaito or if they were taken from Detective Conan? Because I noticed some of the tracks were used in Conan before. I'm only a little over 400 episodes in on Detective Conan after watching it for a little over a year. So it would make sense as to why I can't tell if some of the music is used in Detective Conan later in the series.
