Version:           1.3.2 (using KDE 3.4.2, Debian Package 4:3.4.2-4 (testing/unstable))
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.8

I will start from example. Let's imagine I have the following songs 

(a) Leonard Cohen   - Hallelujah
(b) Leonard Cohen   - Dance me to the end of love
(c) Joan Baez       - Freedom
(d) Leonard Cohen & Joan Baez  - Joan de Arc

It would be nice if the context list presented while 'Hallelujah' is played contained not only 'Dance me..' but also 'Joan de Arc'. Similarly, it would be nice if context list presented while 'Joan de Arc' is played was not empty, but contained all songs quoted above.

More technically speaking:

- establish some standard for naming artists in case more than one artist sings a song (IIRC juk uses '&' to separate names in such case, I would recommend handling both '&' and ',' as separators and maybe creating some deeply hidden configuration box for split regexp in case somebody wants something else)

- in cases where amarok shows songs by artist X (context-pane but also maybe the artist/album tree) show there also songs which were played by this artist together with someone else 

- when amarok plays song by multiple artists, show in the context pane union of the songs by those artist.


Exact details are to be discussed, general idea is to accomodate the fact that sometimes a few artists make song together - and that such song has nevertheless relation to the individual works.
