Security of files

Hey yall,

I am making a flash website for a record company and am interested in the security of MP3 files that will be loaded into a empty movie clip “sound_mc” from an XML file.

I want this feature on the site so people can listen to tracks but,

How secure are their files via if someone decompiles the flash movie would they have access to the XML, folder of audio files and MP3’s within?

Thanks in advance
