I kinda like the songs more when I listen to them on Spotify rather than listening to them as audio files. Do you experience the same thing?
I also like songs more when they have music videos. For instance PI, before its mv, I wasn't that much fan of it, but after the release of the mv it instantly grew on me.

I agree about the music video thing but not streaming necessarily

Yes.

Not that I've noticed no.

not with streaming

but MVs can make me appreciate the song more, yes

Placebo effect? It's the same song if anything it's lower quality on a streaming site.

The other way around. Local files >>>>
