An
MP3 blog is a type of
blog in which the creator makes music files, normally in the
MP3 format, available for download. They are also known as
musicblogs,
audioblogs or
soundblogs (the latter two can also mean
podcasts). MP3 blogs have become increasingly popular since 2003. The music posted ranges from hard-to-find rarities that have not been issued in many years to more contemporary offerings, and selections are often restricted to a particular musical
genre or theme. Some musicblogs offer music in
Advanced Audio Coding (AAC) or
Ogg formats.
