n. A blog that contains mostly music or other audio content.
Other Forms
In recent years some bloggers have been linking recorded audio files to their blogs, a process known as audioblogging. As in text-based entries, audioblogs are cataloged according to time and date and given a title and brief description, with the actual content being the linked audio file.

Irish is an audioblogger — one of a new breed of tastemakers who devote their spare time to disseminating, free of charge, music that's obscure, unusual, cutting-edge, or on the verge of being forgotten. Irish calls it ''the best music you've never heard."

The principle behind an audioblog — also called MP3 blog — is simple. You find a track you want to share with the masses. You place it online as an MP3 file, which anyone with a fast connection can play or save. And you write a little commentary, which might be pithy or detailed, straightforward or oblique. Think of each post as a whimsical capsule review, with sound attached.

Audioblogging represents the latest stage in the natural history of the music geek.

My name is Jish. Nice to meet you. This is my voice recorded weblog. You can call it my "audioblog", "voiceblog", "voxblog" or whatever trendy term you like. I'll be recording my thoughts, excerpts from books, poetry, lyrics. I may even moo.

If the audioblog focuses on voice content, it's also called a voiceblog or voxblog. If the audioblog focuses mostly on music, it's also called an MP3 blog or a musicblog. If the audioblogger syndicates his or her content using RSS, it becomes a podcast.
