Rule: The minimum draining (play) time for a map must be 30 seconds.But, why do we need to make 2 things, just make a rule that is providing an exception, potential also is not the right word imo, that would cause people asking whether they can have song less than minute or not. Potential could mean remix, lowered BPM or loop.
Guideline: If the potential drain time for a song is longer than 1 minute, the minimum draining (play) time for the map must be 1 minute.
The minimum draining time for a map must be 30 seconds. If original version of the song is longer than 1 minute, the minimum draining time for the map must be 1 minute with an exception of official cuts.Official cuts = i.e. TV Size. Short Ver. provided by artist
