Yeah, the songs are required to get 20 votes. I'm going to release the ones that did not finish soon, so you could compete the same song in a battle in the future. The reason for the 20 vote limit is mainly a matter of quality control. I cant remember the exact numbers of the top my head, but think you need to have 20 votes + over 70% rating to have a ranking in the hall of fame.... Once you have completed the battle with 20 votes, you cannot compete the song again, even if you did not earn a place in the Hall of Fame (wanting to keep the HOF fairly lean.... you'll get more what I'm talking about in the next version of bandamp).
