Spotify or Pandora


A relative pointed out two music download websites: Spotify and Pandora. I don't know anything about music downloads. But I was hoping to stream hi-rez original artist oldies. I tried one selection on Spotify and it sounded like MP3 quality and didn't seem like original artists were singing.

Please advise. I would love to stream in hi-rez oldies from the 50s and 60s, but don't know if Spotify or Pandora are good sources.

Thanks

I think that the web-based player only provides redbook quality data stream when used with Chrome.
There is more to this that just the sound quality. Pandora's real strength is its algorithms for picking tracks for it's stations. That it what is was designed to do and many people feel it is the best out there at that. Spotify can have better sound quality seems to be better if you are mostly looking to play whole albums or one particular artist. No experience with Tidal but my impression is that it was more for albums than mixing a la Pandora, but I could be wrong.
Two questions. Is there a way to download music from streaming service to hard disc? Does Tidal stream its highest SQ just running the Tidal app on IPad?
I had great sound running Tidal through iPod touch. I read that you cannot download from any of the three sites.
