Both Tidal and Deezer for sure allow you to download tracks and complete albums to your device providing you have storage room, in most instances a phone or tablet.
These downloaded tracks you can replay without a data connection being present BUT you do need a current service subscription for them to work.
So I connect my phone via Bluetooth to the car stereo and playback the downloaded tracks via my phone/Bluetooth to the car stereo and it works flawlessly.
So let us be clear you cannot download them from your device to a usb drive for instance, you do not ever OWN these tracks, you are still just renting them just as if you were using their live streaming service but yes it saves on your data usage definitely
