Spotify premium is my go to for background music and OTG, or anytime I need to connect via Bluetooth. I’ve found Spotify’s library to be second-to-none among streaming services, and it’s high quality option sounds pretty good. I had Tidal Hifi for a year or so. The UI was clunky but for critical listening it did/does sound slightly better than Spotify. Their use of MQA irked me though. It’s not that MQA sounds bad, it’s the proprietary part of it and the fact it requires special - and usually more expensive - hardware. I got in on the North American beta of Qobuz and have stuck with it. There are interface bugs and a few holes in their library, but both of those things have noticeably improved in just the 3 months they’ve been live in the US. Also, I think they sound better than Tidal in apples-to-apples comparisons (Redbook-to-Redbook for example, yes I know each could have different masters but the difference is consistent).
Long story short, Spotify for background and OTG, Qobuz or local FLAC (for the few holes in Qobuz library) to kick back and get lost in the music.
Also, can I add how amazing it is to live in an age where the world’s music is just a few finger taps away? If you had told 12 year old me that would be possible I wouldn’t have believed it.
