This is an old bug that did not move for a considerable amount of
time. Therefore this issue is marked as 'needs-progress'. We will be
monitoring this issue for the period of a month. If it does not gain
substantial momentum up to that time, the bug will be closed as 'dead'.

Notes about the bug:
The discussion about this bug has gone pretty far. So, what remains to
be done it giving the colorscheme a proper name and get it included
upstream (which is cmus-unofficial currently; the unoffical
maintainers can be reached via the cmus-devel mailing list).
