River Deep – Mountain High

This Recording's most common spelling among linked Track Titles is "space minus-hyphen space". On the only Release with this Recording in my hand, the liner's Track Title is "River Deep—Mountain High". The punctuation is clearly an emdash with no surrounding spaces. I won't be surprised if other Releases used different typography, but nor would I be surprised if emdash is often used in other Release, but earlier MB contributors typed the less-correct "space minus-hyphen space" out of expedience.
