Album Appreciation app for iPhone and iPad

Album Appreciation is an app that includes several lists of essential albums across a wide variety of genres and decades. These lists include 101 essential albums, Rolling Stone Magazines top 500 albums (2003 and 2020 versions), National Public Radios list of 50 essential classical albums and separate lists of essential jazz and bluegrass albums. The app keeps track of whether you have played an album, when you last played it and how many times you have played it and displays a chart showing a count of the number of albums on one of the essential album lists or on your own list of albums (or songs on those albums) you have played, in total and by genre or decade.
