Comment 2 for bug 872006

sorry, one addition.
this is a feature which is very simple, but adds a lot value, it is very significant.

i think if i were fluent in c++ and if i did know mixxx codebase, the db, i would add it like, not more than in a couple of days. may be i am wrong, and there's a lot of things to damage.

but still, please understand that this is really must have attribute for dj software.
