You can now access 60 years of Billboard chart history on your iPhone. Released Thursday in the iTunes store, the Billboard Chart App features 15 charts, from the Hot 100 and Billboard 200 to genre rankings and ringtones. Users can view 60 years of chart history, search by artist, album or song, view ranking details, listen to 30 seconds of music and make purchases directly through iTunes.

"Our charts are already a huge draw on Billboard.com, whether for music discovery or as a measure of popularity, so it makes sense to apply them to the easy navigation of the iPhone, where users can access them on-the-go," said Editorial Director Bill Werde.

The Billboard Chart App is updated weekly with Billboard's traditional chart release schedule and features each ranking's previous week's position, number of weeks on the chart, and peak chart position. Users can search for specific artists, albums or songs, and search by date.

Ten of the charts are available free of charge, with access to the top 10 positions of those charts, going back three months. These charts include: Hot 100, Billboard 200, Digital Songs, Radio Songs, Dance/Club Play Songs, Latin Albums, Christian Songs, Tastemaker Albums, R&B/Hip-Hop Albums and Ringtones.

For a monthly subscription of $1.99, users can "unlock" the Billboard Chart App for extended chart information including:

-- An additional five chart genres (R&B/Hip-Hop Songs, Pop Songs, Country Songs, Rock Songs and Rap Songs)

-- Sixty years of Billboard chart archives

"Anyone who wants to follow the music of the moment, or tap into a decade or genre or artist, can easily search, listen and buy," said Werde. "This app is the entire history of Billboard charting at your fingertips."
