How do you search the musics on youtube ?

For example, I did search for "samurai collection" on pintunes, and I could play the entire music "Duel - Kiyoshi Yoshida".

But I didn't find this music anywhere on youtube!! If I search for "Duel - Kiyoshi Yoshida" or "Duel - samurai collection" I don't get the music in question.

What is strategy do you use to find the music?
