set alarm to specific song

i know that it's possible to achieve this by creating a playlist with a single song in it, but this is bonkers.  almost every single alarm app you can download give you the option of choosing a song you'd like to wake up to. it's the most obvious thing someone would want in an alarm app.  most also include a slow increase in volume to some threshold and a repeat, so that it doesn't turn off if you don't wake up.   it shouldn't include a ton of extra keystrokes if i just want an alarm to wake me up with a specific song in the morning.
