Hi, are there any commandline ncurses musicplayers available for n9. Especially i'm interested in mocp - moc.daper.net - would this be possible to run on harmattan?

I don't see why not. You could try to compile it in scratchbox and see. It's often just a matter of apt-getting the necessary -dev libraries, and running ./configure && make (no different from compiling for the desktop).

If it builds easily I'm sure you can persuade someone to package it.

[edit] on second thought I think getting the necessary -dev packages for codecs might be a pain (it seems no one has yet packaged these for Harmattan?) and ones packaged for Fremantle would have to be used instead. Some (quite old ones) can be found here: http://sheeplauncher.net/debs/
