Hi Janet,
Thanks for the welcome and taking an interest.
Currently all the music is available in most online stores/streaming services (iTunes, Amazon, Spotify, Googleplay etc).
If you'd like to listen for free both Spotify and Googleplay have non-premium accounts where you can do so but there will be adverts. Alternatively if you have an Amazon Prime account you can listen for no extra charge there.
It's also been added to the stores below, I've no experience of their services but they might also offer free streaming.
"Pandora, Deezer, Tidal, Microsoft Groove, ClaroMusica, Saavn, MediaNet, Applemusic"
Hope this helps
Oliver
