peter has said on this page and previously that they're working on an automatic metadata fixer, so you dont have to do it yourself. even if they weren't fixing songs one at a time is a last resort, there are programs to help, and if it comes right down to it ctrl+v then next is a very simple and useful (albeit it boring) command for doing many at a time.

i'm sure i'm not the only one who is incredibly impressed with what instinctiv has achieved already and excited by what is promised to come, please dont try and divert the project onto a completely different track simply because you cant be bothered to clean your own files, if what you seek is a completely dofferent player then go seek a different player, dont kill the potential of this one.
