I use iBroadcast[0], it's a service dedicated exactly for this. Costs me a bit each year but I've felt it worth it. There's some differences to organising in iTunes like the handling of compilation albums that I'm not so fond of but you can see how it works on the free tier.
The browser client only does 128 kbps streaming but their mobile client can set the streaming quality (I have it at 256, max is 320) and I'm working on my own PWA client using their API that I've also set to 256, which would work on both mobile and desktop.
You can also set the browser client to stream the original file directly but browsers don't play most of my formats like ALAC so it just doesn't play anything then.
From the "outside" this looks like such a strange product. The landing page is very obscure and, together with the name of the service, I would automatically think this is a super old school product (being generous) or some sort of weird scam (being overly critical). There are no docs or pictures or any further description of what the product looks like, I guess the authors expect people to sign up to see (it is free! :-).
Other than that, I wonder how they address their costs [0]. It seems free accounts have unlimited uploads. Anyway, I guess I'll have to give this a try to learn more about it.
EDIT: I found some pics by clicking in their facebook page, which in turn links to a news page [1] (...).
EDIT: This product is fascinating. Seems like they've been around for 12 years, have a bunch of loyal users, and support their product (?) via reddit (at minimal approve of the reddit channel since they link to it themselves!). I wish we could know more about the team behind it. Related: [2].
