Like @Vilen, I use Spotify Premium for most of my listening and finding new music these days. I have a fair number of tunes from iTunes and Amazon on my HD, but these days Spotify rules my listening roost.
I like the Daily Drive and the Release Radar to help me listen to new possibilities.
I was slow to develop affection for Spotify, since my music tastes exclude almost all current hit music played on the radio, preferring smaller folk, blues and Americana artists.
I recently spent two weeks in Scotland and I came home with new names of Scottish Artists I heard over there, and lo and behold, Spotify has just blossomed with offerings for me with folk/rock/ Irish and Gaelic artists - How did I ever miss Runrig for so long?? Start with "The Cutter and the Clan"! And Julie Fowlis. Alba IS Gaelic for Scotland. Listen to Runrig sing their signature song, Loch Lomond! 😍
My stereo systems were large pre-digital Klipsch speakers and multiple NAD pre-amps and power amps scattered about my house. Now I have multiple Sonos systems and Bose speakers powered by the Sonos Amp.
My iPhone now has 16 different Bluetooth connections for powering my music, in my home and my vehicles. What a feast!
My older systems get signals from AudioEngine's Bluetooth B1 receivers - they work great! I tried several of the cheaper Bluetooth receivers with poor results, either in audio quallty or connection relialbility, but the Bluetooth receivers with Qualcomm aptX HD innards really rock
On a slightly different note, @slamdunk406 seems like the only poster to say he uses Apple music. I have been wondering if I should try it, since with Catalina, the iTunes store really doesn't offer much that I am interested in any longer - all the obscure, smaller less well know blues and folk/country/rock artists are no longer featured or recommended in my iTunes store now. Anyone else notice this? I really don't want to pay for both Spotify and Apple music, and right now Spotify gets my vote. Should I reconsider?
