How to upload my music mixes to SoundCloud on DaftCloud

I have an imac 3.7 GHz 6-Core Intel Core i5 with 15.3.1 (24D70) loaded.

In order for me to use the SoundCloud app, I use a provided app DaftCloud.

SoundCloud allows 2 options to interface with my imac

1. Spotlight, which is new to me, despite the fact that it is and has long time been in each and every Mac OS.
2. Saved Search.
3. Thanks for any assistance. You might have done this with another user's quick tips and a list of the procedures in hand. Personally I'm trying to correctly order and fold amino acids into molecules here.
