iCompositions has announced the launch of Artist Podcasts, a premium service that lets artists syndicate their music through iTunes and other podcast-tracking applications.

For $4 per month, artists can host their music on iCompositions. It will be put into a podcast so fans can download the songs to their computers and iPods automatically.

Every podcast is submitted to the iTunes Music Store.

iCompositions is a community for users of Apple’s GarageBand and other Mac music-creating applications. With nearly 20,000 songs shared, it is a resource for musicians to get feedback on their music, spread the word about themselves, find add-ons to GarageBand, and interact with other artists.

More information is available at the iCompositions site.
