Napster is gone and is some AI company now instead apparently. We should drop our handling. Even if they do music again eventually it will all look different anyway.

Original description:
Napster links redirect to things like https://web.napster.com/artist/art.69299?catalog=us now, which we don't accept - as such, we should figure out what are all the formats and adapt our handling code. Reported on the forum by friedelfreiraum.
