Get all local music from iPhone Same Like UIDocumentPicker Without UserInteraction

Hello,

I want to fetch all local music files from an iPhone device. I tried MPMediaQuery but I can get only that file which is in the document folder.If we use UIDocumentpicker we can fetch all files from the iPhone (downloads, File Application)after selection by the user.

I want to fetch all music files like UIDocumentpicker but without user interaction. Thanks in Advance for your guidance.
