How much can we trust streaming services for their high quality tiers 2020-01-01 21:15:26 Hello there,I've been reading this discussion about the state of Google Play Music purchases which triggered the next following logical question:How much can we trust streaming services?We all know different services (Spotify, Tidal, Google Play Music, etc) have different quality tiers based on different factors: price, settings, etc. Most stream their default quality version at high enough bitrates that the music should be transparent 90% of the times for 90% of the listeners. Some offer high bitrate versions or even more than 44.1Hz/16bit versions. But how much of those premium versions (or maybe even the standard) can be trusted as being what it is claimed? Or is it all a amalgam of better and worse with some albums having relatively low bitrate lossy versions as source for all their available version (even 24bit lossless)?Yes, a bought album can be analysed via its spectrogram, can be ABX'ed against a CD ripp. But with streaming? I can't think of an easy way.Somehow, what I know already makes me think that the good old CD is the only one to be trusted and will still be for the foreseeable future. This feeling is supported by the state of music tagging that these services offer: just search for the band "Autumn" and see what a mess it reveals.What's your opinion on the matter?Happy new year!
