I'm not an expert,but I've heard before that the vinyl sound is slightly different from the one you can hear on cd/in your headphones. "High" sounds are a bit different, and personally I can hear this light difference: when I'm listening a single on the cd and then I'm listening the same single on vinyl, it sounds a bit different on some moments,and I prefer the vinyl sound.
I'm collecting vinyls of my favourite singer (and want to start collecting some vinyls of my favourite Soviet singers as well), I started to collect it at the age of 13-14 y.o.,so already have a pretty big collection

also, picture vinyls were very rare something like 15 years ago,and I was really happy to get some of those picture vinyls but now they became very popular. Picture vinyls, "marble" vinyls, transparent vinyls, colour vinyls...they all look very beautiful, it's a pleasure even to keep it in your arms

. Plus, some artists have very rare colour vinyls that you can only preorder in advance if you collect different stuff with your favourite singer/band. Latest one I got, was a golden vinyl and also a very rare red set of vinyls of my favourite singer - it looks amazing!
