In a music workstation like this... wav!
You also see ogg, mp3 and other formats but not for doing a remix of a final track. You just don't use a lossy format for a final track. Ask your friend to render as wav.
It's too much hassle to deal with mp3 from our side because of the license as musicbear already has pointed out. My advice is to just get used to it.
PS. Didn't any of the converters work?
