I'm always looking to discover new music, but I really just want to find the right stuff for me. I always find myself skipping through whatever playlist I choose because I'm either bored of the music or it just isn't for me. It would be super useful if some sort of double-tap to like was implemented, sort of like an instagram post. This would really help whatever algorithim is used to create things like our daily mix. If we double-tap to like it we obviously like it, give us more of it and we're more likely to keep paying for that next month of premium. I get that there is also a save feature, but I find myself not using it because I worry that later down the line I'll be moving on from that style of music and it's too much of a hassle to go back and unsave each song. On the other hand this new system could make it easier to keep up with the new style that I may be into and more reason to get back on Spotify.
