which one gives better sound quality, Spotify or YTM

OGG is the container, not the Codec for Spotify. Spotify actually uses the Vorbis codec with OGG as the container.

Anyway, YTM is switching to Opus from AAC so that's a better comparison. You can generally refer to this image.


After 128 Kbps for stereo it doesn't really matter TBH, especially for the advanced ones. But I'd bet on 256 Kbps Opus or VBR AAC over 320 Kbps Vorbis to be slightly better.

Anyway, I'm not an audio expert and there are better informed guys than me.
