How to sell different versions of a song on one page?

Hi everybody,
Maybe a stupid question, who knows but I am really wondering how to do that? Take a look:

Thanks in advance.

Hi,

Once you've uploaded, you need to send an Associations Request to support@pond5.com

Put "Associations Request" in the subject of your email

Then in the email link the files you want associating using their ID numbers, also include your email address.

Oh, thank you! Could you also please advise how to post "mini-players" in description. For example:

Also, in some pages I've seen this players that we have on EDIT Page. Could you please explain how to insert the?
Thank you!

Anyone? :)
