I actively thumbs down the 99 of every 100 tracks I don’t like, the services still don’t get it.

I really wish I could use an LLM to select the recommendations

I am afraid LLMs generally don't have a good idea about music, it seems to select based on similar genre cues and texts more than anything else.

I've been using https://www.getsubwave.com lately and it's great, but it is unfortunately already pre-filtered to my music collection. Would be slick to connect to spotify or a streaming service though!
