Hey so I actually wouldn't upload that Who track the manual way. When I was making the track, I made the image too large and it crashed my table trying to generate the thumbnail. Had to reset it. I was told I would not have that issue uploading through the community though so I am waiting to download it like you are once it gets approved. As for other tracks that are not in the community, you can upload manually using a web browser. this is much easier to do on a computer.
follow this link and scroll down to Connecting to your Sisyphus with a browser. There it will tell you what you need to type into your address bar to access your table. From there, you go into settings > advanced > upload track. you will only see the upload track option if you are accessing your table from a web browser. Choose the thr file and boom there ya go. the link below tells you a few different ways to create your own tracks. (hint: you don't really need to be that artistic to do what I did! Im not lol) it also gives a list of some popular artists and the thr files to their tracks. Hope you enjoy!
