soundtrack album pop music
A vast number of recordings have been issued under Presley's name. The total number of his original master recordings has been variously calculated as 665 and 711. His career began and he was most successful during an era when singles were the primary commercial medium for pop music. In the case of his albums, the distinction between "official" studio records and other forms is often blurred. For most of the 1960s, his recording career focused on soundtrack albums. In the 1970s, his most heavily promoted and bestselling LP releases tended to be concert albums.
