You can already set up a website using a "website builder" which hosts it for a couple of bucks and doesn't force any branding on it. A site on Squarespace costs $8/m and gives you unlimited storage and bandwidth to distribute your music; for $18 more, you get to use the ecommerce part to sell your stuff.
If artists aren't doing this already, which is much less intrusive than Soundcloud/iTunes/etc, what makes you think they'll be hosting their own IPFS sites?
Because you said server, and the solution is serverless. $8/month is still $8/month. I'd rather that anyone who was interested in my artistry just come and get it from me, directly. Remember the aim is to eradicate the middle man entirely. You have not done this in your position.
Artists don't get paid, piracy or no-piracy. The middlemen get the majority of the profits in the MPAA-protected mafia industry.
Putting tools in the hands of artists that provide them with the ability to contact many, many fans, and be assured of that relationship without interference by a 3rd party, is quite a valuable goal. Thankfully I'm not the only one with that aim.
Like I said, artists could already bypass the MPAA-protected industry and get a much larger share of the profits and direct contact with the fans by setting up a site as I mentioned before.
If they don't even do that, I think it's unrealistic to assume they'll start using IPFS and host their own stuff.
