Ok guys and gals, the way this one works is when you download it to the IMVU previewer, you will be immediatly in a tab called "special".
1. Look down that tab till you see a browse box next to a "sound in" box. Press the browse button to it to add your own ogg music files.
2. Hit "apply changes" at the top of the previewer to make sure your sound is in.
3. File -> Save as. Save your .cfl(product) file somewhere where u can find it easily. You will need to upload this when you go to submit your product.
4. Click the "Submit product to IMVU catalog", button. A web page will come up with different settings such as description and tags. You will need tp upload a catalog(100*80) picture and the cfl file you saved.
Now your done
Explanation

Two notes
1. Again this is triggerless so all you need to do is hit apply for it to work.
2.I have said this once and I'll say it again. Pleas do not outright purchase this product as there is no music with it and unless you are a developer, you can't add music.
