The original Japanese title: シルクロード少年 ユート can be translated as "Silkroad Boy Yuto" or Romanized as "Silkroad Shōnen Yūto". Also, this anime has an alteramenate title "
Silkroad Kids" which refers to the ©Silk Road Kids Project.
So the title should be either Silkroad Boy Yuto (Silkroad Shounen Yuuto) Original Soundtrack or Silkroad Kids Original Soundtrack, but not a mix of these two titles in one.
