Why do I have so many errors in my log?

[Mr_Withers]

I've got rid of the majority of the errors, here's a selection of some of the remaining ones. Any pointers would be great!

This first error is the most common type, there must about 50 errors of this type.

Error: unexpected end of file at offset 0 in file import/2014-12-09/Dan Auerbach/Keep It Hid/11 My Last Mistake.flac (length 0)

half a dozen like this one below....

Warning: ignored conflicting DISCSUBTITLE value Arne Domnérus, Bengt Hallberg, Lars Erstrand, Georg Riedel, Egil Johansen 22:40 in file import/2014-12-09/Arne Domnerus/Jazz at the Pawnshop/Arne Domnerus - Jazz at the Pawnshop - 09 - Stuffy.flac

Maybe 25 like the error below.....

and lastly

Warning: conflicting ALBUMARTIST values ignored for file download/highresaudio.com/Emmylou Harris & Rodney Crowell/Old Yellow Moon/Emmylou Harris & Rodney Crowell - Old Yellow Moon - 08 - Bluebird Wine.flac
first conflicting value: Emmylou Harris
second conflicting value: Rodney Crowell

I know the above error in the same as the one I posted earlier, but if the album artist needs to be unique and Emmylou Harris & Rodney Crowell are the 2 artists in question I'm confused about how to make it work correctly. There's half a dozen albums left like this one.

Thanks in advance
