I noticed that currently, the track links in release (/all/) embeds lead to a non-existent page. For example, at https://faircamp.sny.sh/starlab-legacy/embed/all/, "1. Relaxing Beats" leads to https://faircamp.sny.sh/starlab-legacy/embed/all/1/.
In 5aa03e3d4c I updated the link to point to the correct URL (I hope I didn't miss any edge cases).
I also set the links to open in the parent context (i. e. the page the embed is located in, instead of the potentially very small embed itself) in 65128dc08b.
