It means that Just Dance 2014 only uses a variety of dancers, which means that it uses some dancers only, but not all of the dancers. For example, TiK toK hasn't appeared in any JD2014 mashup, so it's not one of them. The song in the brackets next to the song means that it has appeared in that mashup.
