Hi, I found this Spotify playlist a few days ago ("Most Beautiful Songs According to AskReddit"). While the choices are obviously debatable, there is certainly something in there for everyone. I am not sure if you can listen with the free Spotify (I have the paid subscription). My understanding, however, is that it is also available on YouTube, although I did not investigate that:
