iPhone is an interesting platform for musicians, because it enables a fusion of music and technology, creating new possibilities for musicians and for the audience.

Apple's App Store allows anybody to upload a new application online and distribute it for free or for a fee through iTunes.

The real potential here lies in the new music applications, which could combine music, location-based services, and the internet to propose new ways of experiencing music and sharing it with the others.

A good example is Ocarina, the musical instrument, which lets users play it at the same time over the internet.

Another example could be an album release, which would play a specific song depending on the location of the user. This way, a band could create a true site-specific experience for its listeners and even monetize on it.

This recommendation system allows bands to create online communities, build up associative network around their music, and promote it next to similar bands, venues, writers, philosophers.

A band can create a cluster of inter-related items around their own profile and promote it through posting events and linking to related profiles.

Last.Fm is a useful platform to promote one's music. It's also a great recommendation tool that can successfully perform the curatorial function that labels used to do before.

Bands can create their own profile, upload their music, build a community of fans, stream latest news on Last.Fm, and pay a small fee to have their tracks played in online radio next to similar bands.
