You need to add ID3 tags to your MP3 files. There's an app called Music Sense available in Store that can do that.
Install it on your phone, open it, tap on "...", then tap on "My Music".
Browse to the song you downloaded and tap "Get Tags" (found below the image placeholder) (Requires Internet).
When done, tap "Save" and you're done.
The downloaded songs will be stored by default in
SDcard->Downloads. Navigate to the folder and move these songs to the location
This will help the Xbox player to identify the songs easily. You can do this easily by using the Files app.
