Well , what i would like is a MJ12 who will look like a MC 12 music only part
The only extra being the resize Art Cover.
Now ,if it is a good project for you , even as a pay jukebox , this is another story.
Concerning the free jukebox as it is today , i do think than the resize art is a good thing to be , because it keeps the user inside the program for all tags.
On your side , you have to think Itune ,WinAmp and ,Monkey player( or a name like it). as free players in the league of MJ12.
They do not have secure rip, rip to one file +CUE
MJ 12 interface is much much better ,cleaner than the 3 others.
few small things they have - or some of them have - are :
-Locate file ( external inside jukebox is enought)
-library Tools File properties from filename and rename files from properties.
With this few fonctions added , i'am sure , MJ12 will stand against the other free players , and by far.
you know i use to complain about MC 12 being a mess to look at.....
With MJ 12 you got a clear, friendly interface , it looks pretty , really.
