MP3s don’t have any of those problems. You just copy it to whatever device you want to “stream” it from and listen to it with no account or subscription.
…sure. Yes. If you own a song, you can listen however many times you want, simultaneously or not.
But streaming services are simply a different value proposition. Listening to an mp3 means either buying all the music you listen to or pirating; it also means having the music stored on your listening device in advance, or streaming from a personal media server. I listen to a lot of music that I haven’t heard before and don’t know if I’ll actually like; I also listen on my phone a fair amount and have a limited amount of storage space for music. For that use-case, streaming is preferable (to me).
Yep I know about all of that, and I have zero streaming service accounts because they all suck in comparison to actually owning the music I like. I’ve tried them out, and it’s just too lame for me to put up with their bullshit hassles. The companies selling those subscriptions love that you will keep paying them perpetually to gatekeep your access to music.
I mean…okay? My whole point is that “purchase a bunch of music to own forever” and “pay a streaming service to hear a bunch of music once” are totally different use-cases. It’s great that you own music. Good for you. I own some too! But streaming fits my needs better overall.
And all of this is completely beside the point that it’s really not that weird that the cost for two people to stream is higher than the cost for one person to stream.
