What does (Talkover) mean? What does Var.1 mean?

Talkover versions in the Proud Music Library contain less hooklines/melodies in comparison to the normal version of the specific track. They are more suitable for background use, e.g. for narrated text. Variations are based on the same song, but may be different in character.
