Not for all types of sound: I mentioned one of the common problems with sounds which ramp up sharply, which is not something VBR can solve. AAC also has pre-echo issues (all DCT-based formats do) but the designed was improved to reduce them since this was one of the known problems with MP3 which you couldn’t just throw bandwidth at.

My larger point was simply that most services use AAC now because it saves them money, fits more music on your phone, and has better sound quality. MP3 is good enough for a lot of things but there’s no point in supporting two formats when both are widely supported and one of them is better across the board.

I don't disagree that AAC is better, but other than iTunes most people buying from the stores mentioned on this subthread are buying MP3 (if not lossless).

Perhaps - I haven’t bought MP3s since the 2000s since sites like Bandcamp almost always offer lossless or AAC — but I was also thinking about how almost all of the streaming services use AAC, too, and that’s a huge chunk of people’s listening.

For sure, but the context here is owning files - not listening to music in general.

Looking at Junodownload/Beatport/Bleep they don't offer AAC at all, that's a little surprising.
