Just reporting back, your initial solution works for me so thank you very much! I don’t think I’ll have any need for your second solution but is valuable for some other community members. You raise very good points to ponder.
I planned to have around 200 different songs but after adding around a dozen or so, I discovered the project was growing in disk space quite drastically. Unreal blows up 1MB .ogg files into 20MB monsters for some reason so a limitation there. Your solution is just wat I wanted thanks again!
