I'm new to iPhone and I'm wondering if it is possible to play or have access to music files I downloaded from a 3rd party app like: Spotify, Apple Music, or Google Music. I am a long time Android user and this wasn't an issue to do. Once you downloaded music and stored it on the phone the app of your choice which I used Google Music a lot included those songs into my Google Music library. On the iPhone this is not the case, I do not see the files at all on my phone only in the 3rd party app music library that I do not want to use do to the fact you can't include other music outside of the app. Hopefully this was explained semi-well and someone can help me out. Basically in a nutshell, I'm trying to play songs I downloaded from My Mixtapez to be included/synchronized in the library of Google Music, Spotify, or Apple Music preferably Google Music.
