SUMMARY
Not a serious problem, but irritating for sure.
To start playing a specific song in the current playlist using the touch screen you need to
1. Tap on the song once to select it and show the buttons that normally appear on mouse hover
2. Tap on the play button that just appeared, **but doing so will only select the button and not press it** (this is the irritating part)
3. Tap it again to actually start playing the song
The same goes for the other buttons in there, like "show in folder" and "Remove", as well of course.

EXPECTED RESULT
First of all, in step 2 above, tapping any of the buttons should just activate it, you know, like buttons usually do when you touch them, instead of only being selected and requiring another tap. That way you would only need to tap a song twice to play or remove it.
But the following gestures could make this even faster and easier (should I create separate tickets for these?):
- Quickly double tapping a song should immediately start it even if you didn't actually touch its play button. After all, so does double clicking with the mouse
- Swiping a song to the side should remove it from the playlist
