This is a great music player, however the latest versions all have this issue:
Playing music normally, mp3 or flac, only eq is enabled, or not playing music at all - makes my cpu run constantly at around 20% (4 core i7, win 8.1).
I have tried play around with settings, restarting etc, but the issue still remains.
Update: This issue was with the release canditate versions, now I completly uninstalled Musicbee and installed the 2.3 and it seems to be OK. So the issue is with the 2.4.
