pretty simple solution (unless nsoul already owns the songs). change the name of his band...
Well, for obvious reasons I was not privvy to all the gory details of the mess. I know that he self-published a few projects under different names, but they were both different styles. (One is ambient/soundscape, and the other is... something else entirely. Both are good though...)
Anyway, now he seems to have retired from the music scene altogether. IIRC, he used to maintain antidotegroove.com, but then he posted a retirement notice. Now it's been grabbed up by the domain vultures and that's about all she wrote.
So, while there are various and sundry clever ways of wriggling out of a problem like that, none of them will help if the problem itself manages to break your spirit.
I feel genuinely sorry for any artist that NSould manages to con into their... whatever they're offering now.
