Tidal, Deezer


Could someone with experience with music subscription services please advise. My confusion is that these music services advertise that you can download music for offline listening. Wouldn't that be putting music files in your storage...creating a music library? I have had itunes and rhapsody, both of which you can download music files into your computer. Surely there must be others you can do the same? Thanks for any advice

I have just verified on my laptop that Tidal does indeed NOT allow offline downloads to a "normal" pc.
Bummer......
Tidal states offline is only on smartphones and tablets...but your spotify goes on to your computer for offline listening?

Repeating myself here...
downloaded Spotify albums that are listed under Playlists are available/playable off-line on my MacBook Air.

It sounds like Spotify does work on anything offline then.

I am fairly sure if I added Tidal to my old Samsung Galaxy tab it would have offline available there but it is NOT on my laptop.
Hey uberwaltz - 
You might be right but I have to stop short of saying "anything offline" as I've only tried offline Spotify access with iOS devices...MacBook, iPhone and iPod.  I'm kinda surprised about Tidal not working in similar fashion. I wonder if it has to do with file sizes.   Ogg Vorbis format used by Spotify crunches things down to a pretty small file size.  
Can anyone tell me what the fascination is with "downloading files"?
I guess owning music? Is better than streaming music? I find that by exploring hundreds of artists on the fly and listening is very enjoyable.
I don't see any benefit to building my own library of music, when I have a much bigger, growing library of music at my fingertips ready to be streamed??? Especially with the quality of many Tidal MQA albums...
