FINAL REPORT
I made the playlist "Acoustic Sessions 104" in Retro Music with the five songs in the order you asked for: Echoes of Silence, Forever Young, Endless Summer, Voices in the Hall, then Rising Sun. The playlist page shows "5 Songs • 18:39" and lists them in that order. I then exported it with the playlist's "Save as file" option into Downloads, and the Files app confirms the file Acoustic Sessions 104.m3u (423 B, saved at 15:35) is there.
