What is a unique download?

SongSelect® Advanced and Premium subscriptions include 200 unique downloads per year. A unique download refers to an individual song with its own unique song number. The first time you print or download a song's chords, lead sheet or vocal sheet, it will count towards your 200 limit. If you subsequently download or print further copies of the same song, even if you change the key, this would not count against your 200 limit during your current subscription year.
