Phone with android 4.4.4 'generic' music player only plays music in internal storage audio folder.

[AC Question]

Hi, I have a Huawei Ascend Y550 with android 4.4.4 The 'generic' music player will only play music in the internal storage media/audio folder. i have created a second 'media/audio' folder on my SD card but even though it sees the files neither Google Play nor the generic play the audio files. Can I change the settings for the audio player from where to retrieve the files?
The SD card has been mounted as default storage and the phone is set as a Media (MTP) device.
TIA
