With regards to taste, you usually need to find a suitable gateway into an unpopular genre to begin appreciating it. I always hated jazz until I turned 30, when I heard the melodic jazz of Avishai Cohen [1] and Phronesis [2], which led me to Eric Dolphy [3] and ultimately to free jazz outfits like Alexander von Schlippenbach and Peter Brotzmann. Having grown bored of everything else also helps.
I recently cancelled my paid subscription to Spotify after 10 years and I use Youtube a lot now. The Spotify web app is not great and Youtube recommendations are a lot better in my opinion.
