Music with Loops, how to upload

How do you upload a song that you'd like to split up into loops, along with the main file. Do you make a collection?

Ask the reviewer to associate them all together and they will be grouped when the music is approved. Making a collection also wouldn't hurt.

I guess I worded this incorrectly. I've already uploaded the loops separately and they were approved. Is the next step to just make a collection?

I'd say so if I understand what your saying correctly.
