Listen your music in iXpand in iPhone or iPad

If you want to offline play Apple Music on iPhone or iPad without Apple Music app, you can convert Apple Music to MP3 or M4A at first, and then using iTunes to sync the converted songs to iPhone or iPad.
I have ever used this UkeySoft Apple Music Converter to remove DRM from Apple Music, and then convert songs to MP3. After get the DRM-free Apple Music, I can use iTunes to sync the converted Apple Music to iPhone, iPad, Apple Watch and iPod Nano.
