I've been using iTunes Match for 2 years now which means that you can upload all your music from CD via iTunes to the cloud.

It costs £25 a year and it means that you can manage what songs are on you iPad or iPhone without wires. Just simply download what tracks you like or stream if you have limited space. It's like a personal Deezer that only contains the music you own, so not to everyone's taste

Yes Deezer, Spotify, Apple Music etc etc offer more in terms of music but iTunes Match plus a little Amazon Music have been fine for me as an old fart.
