Since maximum scores for each song are normalized 50,000 regardless of difficulty, overall scores on songs can be compared. To achieve the "gold record" for a song, 12,500 points must be achieved. To achieve the "platinum record" for a song, 20,000 points must be achieved. Winning records will unlock additional characters, outfits, and songs. In "Karaoke Revolution Party", "Karaoke Revolution Country", "Karaoke Revolution Presents: American Idol", and "American Idol Encore", 50,000 points (a perfect score) earns a "diamond record". In "Karaoke Revolution Presents: American Idol Encore 2" the point system was changed so that 60,000 points gives a "platinum record" for a song and 100,000 points is a perfect score ("diamond record").
