What is really the purpose of streaming??


What is really the main purpose on streaming?? Is it just a big convenience to have music and artists at your fingertips? Is it that you get a better sound than cds? What if you have a cd player with an exceptional DAC built in like the Rega Saturn R . To me when cds came out i never looked back on my LPs. I thought cd playback was the best. Now i hear alot of streaming talk. Can someone clarify this to me ?

Oh and yes you can transfer songs from Tidal to your drive. I've never used this so maybe someone else can chime in here. I use tidal in my home system and have the app on my phone so I have it in portable mode this is where storing the files on your drive comes in so you can dl them using wifi and not use your data.
I stream for pre purchase of CDs, SACD's and for convenience of listening to music I would not necessarily purchase.  In addition to my computer streamer with the audioquest Firefly, my amazon Dot is great as a streamer to my Bluetooth speakers. I can get Instant back round music for just about any genre.  Love it all! 
@lowrider57 you can't download anything from Tidal but on the app you can have an offline queue where you essentially do download stuff but you can only access it through the app. I do that on my phone so I can listen to stuff when I travel if I don't have wifi or a cell signal.
@glennewdick, thanks for answering my questions.
The fact that you don't lose your playlists is a great feature. It's making me think I should stop burning CDs thru my computer.
Previously I didn't think streaming was for me because as I stated earlier, you're only renting the songs. So now I know better.

Didn't mean to hijack the thread, many thanks.
