This was exactly the same question in my mind when i joined IGT. But soon it realized myself that its not possible in forums when you dont differenciate in the posts which are combination of casual communication and of the actual submission.
First of all, no one gonna take the pain of looking each post in each thread to index the submission. And secondly, this style is not scalable at all for the future submissions.
What IGT should look at the way to differenciate the submission posts from chitchat. Whenever someone is going to post, (s)he should be given a different form which explicitly ask for Artist, Song Title etc in proper format and give you area to submit or upload your work. Only this approach can help indexing all the songs sorted by artist or title plus number of viewers so far.
I think that MODs+Admins will consider this suggestion for IGT v.Next.
Actually i find it very annoying so i took initiative to index alteast my work.
