There are 3 players here. The first one is a Pop Player and features songs by artists such as Britney Spears, NSync, Christina Aquilera and the Backstreet Boys. This player gives you the option to have someone on lead vocals helping you (The Britney vocalist is terrible hehehe......I nearly bust myself laughing!) The second player is a Britney Spears only player and you have the choice to have the melody on or off. This the same for the NSync player which is here as a special bonus.
