Dowloable items upon payment

Hi every:
I'm newbie to OpenCart but I have it installed and in some way configured. Now I need to sell CD (phisically and digital - meaning downloable). The client need to see at least this three options:
1. Shipping phisical CD (send to his/her home)
2. Pay and download a digital copy of this CD
3. Pay for some songs and download this payed songs

Can any tell me how to achieve this?
Note: Maybe this is not done at this time in this case wich file(s) need to be changed to get this work?
Cheers and thanks in advance

at this time you cannot do all those options in one product. You could create a separate product for each. As far as telling you which file to change it would be quite a bit more than changing one file to make this happen.

Ok I understood your point for a complete CD one for Physical and another for Downloable but for songs the same approch is needed? This is crazy because I have 15 items for each CD or more :-[ any other comments?

Under OPTIONS in your admin You can make a product have a CD/VINYL/FULL MP3 Download option but i think you need to create a different sku for every individual song with the single download link. You can add the tracks ($.99 each) as options. Im trying to do the same thing but don't know how. I wish i could. Anybody? Anybody? See example www.digital-distro.com
