[edit] How To

Select two users to compare. Click "Battle", and the database will calculate who has a higher ex score on each song.

Each song score table cell features:

• A background color matching the colored name of the user who won the song. (A white background indicates a tie.)
• The difficulty of the song, with a link to View Song which will highlight both users' scores.
• The name of the DJ who won the song.
• The difference in the ex score between the users.

On the right column, you'll see a variety of battle decisions (victor by number of songs won, a breakdown of wins by difficulty, victor by total ex score) as well as a list of battleground songs.

[edit] Battleground Songs

Battleground Songs, like songs within Striking Distance, are songs where the difference in ex score between the users is 10 points or less. The color indicates who won the song.
