Push music tracks into Unity Music lens via Unity Music Extras scopes (support for Audacious, Clementine, Gmusicbrowser, Guayadeque and Musique)

Music plays an important role in our lives, music that, after installing Ubuntu, can be played via Rhythmbox, Ubuntu's default music player.

Nevertheless, along with the recently refreshed Rhythmbox, there are available (via Ubuntu Software Center and/or PPAs) numerous music players, featuring a wide range of functionalities, online services integrations, eyecandy elements, etc.

Using Unity, the Dash becomes important, importance aspect sustained by its ability to present the user needed informations, such as recently played music tracks (consequently, in order to achieve the mentioned exposing ability, the Dash needs data sources, especially for non-default apps).

Unity Music Extras scopes are a bundle of scopes (sources) that push played music-related items into the Music lens, extending the Rhythmbox only-powered Music lens (as the default behavior) to a solid amount of covered players, such as Clementine, Guayadeque, Gmusicbrowser, Audacious and Musique (basically, a wide range of music players, touching numerous tastes and user preferences).

After installing the mentioned scopes, playing music via a supported player (like for instance, Clementine), automatically gathers and exposes the played music tracks in the Music lens.

A definitely interesting aspect of the newly released Music Extras scopes is their up-to-date approach, meaning, right-clicking on a Music Extras-generated item, opens it in its dedicated preview, allowing users to directly play items from "inside" the Previews.

Having multiple music players installed on a computer (simultaneously), tends to create confusion, in the sense of "forcing" the user not-so-easily to discern between exposed music items' origin; Music Extras scopes 1.0 come with a handy approach of displaying (as items' icons) icons generated by music players, meaning, playing (or adding into its library) a track via Audacious, exposes the played track via an Audacious icon, thus presenting itself as an easy method of indicating to users the "owner" of various music items.

Music Extras' usage is as simple as: adding/playing tracks via the mentioned players, adds the tracks to the Music lens, right-clicking on them, opens them in a dedicated preview, directly clicking on tracks, opens them via their handler (like for instance, clicking on an Audacious-generated track, opens it via Audacious, clicking on a Clementine-generated track, opens it via Clementine, etc).
