I understand you now.
I tried to recover Alex's Technics sequences from you using the webarchive but they failed. Sorry, I tried. I will look out for them.
When my new sites launch, members will be able to share their sequences and recordings. Like the cees site used to do but the members will be able to add the files themselves. Well, not immediately when they launch but the feature is built, so it will come soon after launch.
I'm doing my best to add audio preview facilities to many things... we are about music so we should be able to hear music
