Talking about Discover Weekly playlist: I think the recommendation engine is mostly based on what you actually listen to. When I listen for a week to emo rap, I get emo rap recommended in the next one. I think song/album radio is not exactly based on your taste, but on what spotify considers similar. Try making a playlist with your favorite songs and press "enhance" or "playlist radio" to see recommendations based on that context.
