I used VLC in the past but switched to the simple music player after having too many bugs and crashes with VLC on my phone.

It should be possible using the address overlay in the app. Otherwise you could leave a note or use the web based editor on the OSM homepage.

I find it interesting how large the difference between tastes regarding music players is. After the development of Cantata ceased, I was unable to find any mpd client that I liked and decided to write my own instead (if anyone is interested, the code is available at https://github.com/dokutan/cmpdc)

I use both versions actively, the main differences of SCEE compared to StreetComplete are the addtion of more obscure questions (for example building and roof colors, species/genus of trees), allowing direct editing of tags and disabling the gamification/statistics.
