You don't do music discovery by blogs, music journalism, word of mouth, genre databases and so on? You're fully subservient to some algo an ad corp is using?

As for purchasing, many artists give away their works (e.g. "name your price") or don't deserve payment but should be archived and studied anyway (e.g. nazis, billionaires and so on). It's probably not that hard to build a Bandcamp crawler that fetches name-your-price-albums from specific genre tags.

For a few clients and simple browsing you can run an audio cast off a router or cheap SoC.
