MuiscBee was one of the reasons that kept me on Windows but I've finally got it working fine on Antergos (so basically, Arch). Used PlayOnLinux and the portable version of MusicBee 3 on Wine 3.0. I did a x86 prefix (Windows 7) and only needed to install dotnet40 in order to make it working. In order to play m4a files I followed
this.
As for the problem of Chinese/Japanese/Korean characters I imported fonts from my Windows partition folder in the MusicBee virtual drive's fonts folder (drive_c/windows/fonts). The font rendering isn't the best probably due to CJK Windows fonts that suck, but it's still better than nothing. I tried to manually change fonts in the MusicBee settings but for some reason fonts like the Adobe's ones or the Google CJK's ones are not showing up.
A thing that is not working, at least for me, is the "auto-pick panel colors" option. Instead of picking the color from the album's art it directly shows the album's cover in a stretched way. So I needed to turn it off and keep the gray color background.
I also wish keyboard's multimedial keys would work, but unfortunately are not. I'm sure there's a workaround but at the moment I still haven't looked into it.
MusicBee remote (my life saviour) is also working fine, so I'm really happy of the result!
