Remote access to my storage OR at least to my TIDAL and Qobuz playlists

Is there any why I could listen to my music through my mobile phone while I’m not connected to my home wi-fi?
If it’s impossible, how about at least Tidal and Qobuz without my personal storage?

I’ve read some discussions about Subsonic, but I don’t know if could install it on ROCK and/or if it’s the ideal solution.

My set is: NUC7i7BNH, runs core on ROCK; streaming through Lumin S1; storage on external USB Hard-Drive.

Thank you all!
