Why we can't choose the song we want to play?

[DandT]

Ok, so I'll get right into the point. As a free user, I can see you are very limited. Like come on, we can't even choose to play the song we are looking for! I understand the "6 skips/h" and other Premium future, but this is too much. So I wonder why we can't get that as a free users?

I don't want to be "that guy", I'm just curios why we are so limited (and I'm asking that only for mobile)
