Fight me, but I left my harddrives full of ripped mp3s from my youth in a dry closet for years and nowadays 100% stream stuff from Spotify. My musical taste is obscure, but not obscure enough to not be hosted by the service.
When it comes to formats, Bernd, who is a hobby musician and festival enthusiast for a good while (don't wanna brag, but neither I want to hear "You're just an NPC fuck off) found that .ogg ist nearly indistinguishable from .wave/.flac at ~192kbps. Zero difference. Try it out yourself. Feed two channels into Audacity with different codes, switch phases and listen to the difference. If the tiny hiss you hear which is not even distinguishable is the proof that only wave is the true format, seek help.
