Dubmusic Streaming Radio looks to be a custom module so maybe its menu button needs to be controlled from there? Alternatively you might be able to edit the skin's profile_menu.tpl template add it there, outside of the regular menu button loop, so that it shows to all.

Profile 'etienne.gomez' is in the 'To become a fan' quota.
That quota has the Audio module enabled for it.
I'm not getting what the issue is. If 'fans' shouldn't be able to unload Audio items, disable the module for that quota.

I'm seeing that the Audio module is enabled for all quotas and the Audio button is showing on all profiles.
I temporarily disabled the module and the button doesn't show.
I'm not seeing an issue.
Yours is the only site that I know of that is having this issue. You say that people are making purchases but I'm seeing no evidence of them on your site or on your database which makes be believe its down to configuration. It all looks ok in your control panel so what about at PyPal's end. Have you set the corrent Merchant ID in the Payment module's global settings. Also, have you set the correct Notification URL in your PayPal control panel?
