An
online music store is an
online business which sells audio files, usually
sound recordings of music
songs, in which the user pays on a per-song or
subscription basis. It may be differentiated from
music streaming services in that the online music store sells the purchaser the actual
digital music file, while streaming services offer partial or full listening without the actually owning the source file. However, online music stores generally offer partial streaming previews, with some songs even available for full length listening.
