Me and my friend like music. We often share youtube links of songs via facebook. We message these links to each other and in some time these messages fade out of the conversation. It wouldn't be a problem, if it wasn't so difficult to find them later on. My thing is, I want to collect all the songs ever posted in this conversation, so I could for example burn them onto disc. Is it possible to somehow get the data of all messages ever posted in that particular conversation? Something like an archive or a listing of all all all messages?
