File type: eMusic File Format, Pro/Engineer
The EMP file extension is associated with the music files that have been downloaded from the download site eMusic.com. The said files with the EMP file extension are then converted into the MP3 format by the download manager of eMusic. This online music store is known to operate by subscription and has currently more than 400,000 subscribers.
It is different from other known subscription music services such as Rhapsody and Napster in such a way that the downloadable music files are in the MP3 format which makes them completely compatible with every digital music player. The files are also free from the restrictions of the digital rights management software.
The restrictions include burning or copying limitations or expiration dates. Although the online music store has been lauded by the public, its low-price model and lack of DRM or digital rights management encoding have made big record labels frown upon its services making it specialize in non-mainstream music genres and underground artists.
Among its non-mainstream music are pop, jazz, new age, traditional music, underground rap, indie rock, hardcore punk, classical music, experimental music, and electronic which are all on independent record labels.
