MatchRanker

Match-Ranker is a highly versatile and inimitable app designed to help users rank their favorite songs through a series of head to head “matches” between pairs of songs. In each match one song is the winner and one song is the loser. Each song in a user’s universe has a rating score. After each match, the winning song will gain rating points while the losing song will lose rating points. Songs can be compared to each other and ordered in a holistic way by looking at their rating scores, these will continue to get more and more accurate as the user completes more matches.
Each user will have their own universe of songs. Their choices of which songs win and lose match ups will drive a song’s rating within their universe. Each user’s ratings are unique. Their choices will not influence the ratings of songs for other users. A song can be rated highly by one user while the same song has a low rating with another user. These are completely independent.
Match-Ranker will randomly generate match ups of songs from within a user’s universe. For each match up generated, the user picks which of the two songs wins. Every song in the user’s universe has a rating score, and each time it's in a match up, afterward its rating will change according to the result. A song that wins a match up will increase its rating points and a song that loses will decrease its rating.
So it’s an ultimate doorway to your songs universe. Make sure every matchup speaks for you and your favorite song leads the rest!
