Well that was a comprehensive answer!I'm currently on the free service with Spotify and it's getting worse, with longer and more frequent ads, terrible service on my mobile, plus I can't use it on my PC (which I've discovered now is most likely the browser issue}. There's a number of reasons why I've chosen Apple. A lot of people say the audio quality is better than Spotify. They certainly pay a lot more to the artists than Spotify (who are notoriously the worst). Spotify have recently introduced new T&C allowing them greater powers over artists materials uploaded to their platform. Plus the owner earlier this year invested half a billion dollars in an arms company linked to Israel. I know the likes of Apple and Amazon aren't angels either but sometimes you opt for the lesser of 2 evils. Spotify also pay very little to emerging artists (which is the bulk of what I listen to) and indeed nothing at all if they don't meet their minimum stream criteria. There's also a bigger issue with AI music being uploaded than with other platforms. I saw a video the other day that claimed 30% of weekly new music uploads are AI generated. In numbers that equated to something like 30,000 songs every day.
The bottom line is that more and more artists are removing their catalogue from Spotify and many new artists will not pay to upload stuff if there's little chance of getting a return.
I have the same Apple issue as you had (wrong date of birth) and the email linked to my account is long gone. This is why I went to Spotify but after your lesson above I need to look at changing for multiple reasons.
