Not as hard as it used to be trawling through records though. There are music clubs for all genres..with recommendations. Wikipedia. Within 2 mins you can be listening to see if you like it.
You like Jazz, so Google an artists "best recordings". This will throw up niche recordings that enthusiasts like and many clubs etc. Bounce off that and just save what you like ? Sometimes I will save 30 albums and after a couple of weeks have half a playlist full of cherry picked tracks, plus a couple of albums I really like and can listen to in their entirety.
Don't give up. Put the yards in & the rewards are great. Ime
* Learning about the artist & his fellow musicians is as rewarding as expecting a "musical quick fix". The stories are often integral to my own enjoyment.
