The Rock and Roll Hall of Fame and Museum has released an iOS application based on its Songs That Shaped Rock and Roll exhibit. The app features a multimedia showcase of over 600 songs from the 1920s through to 2006 selected by the museum’s curatorial staff and a number of rock critics and historians as influential in the evolution of rock and roll. Users can swipe through the app to experience the music from each era. Individual songs in each decade are presented using an album cover slideshow and users can listen to an audio preview of the song and read about the history of it and an explanation of why it made the celebrated list. Users can build a custom playlist of songs within the app or tap a link to purchase a song from the iTunes Store. Rock & Roll Hall of Fame is a universal app and is available from the App Store for $2.
