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

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.
Think about it, if you could download the music you'd just sign up for a month once year and binge-download. I-tunes is a download service where you pay for each download, Spotify, Pandora and, Tidal are streaming services where you pay for access to content on a monthly basis. You are basically "renting" and get no equity or ability to keep the content.

I've never used Spotify but I agree that Pandora is much better as a radio-like service to just turn on and listen to. I think the SQ of their pay per month service is quite acceptable and I use it pretty regularly.
Love Pandora's easy and logical interface and "good enough" sound. Spotify? Perhaps the worst interface I've ever encountered. Just my 2Cents worth.
