IDEA: Suppport for music stores (R+D)

["Juan A. Suarez Romero" <jasuarez igalia com>]

There are out there a lot of music stores: Amazon, itunes, jamendo, so
on, so on, and so on

Grilo was not designed with this in mind, but hey! It would be cool to
have it.

Something like GrlStore or alike would be the good way to proceed. But
this is a brainstorming, so let discuss if this idea make sense, and how
to approach it.
