Instead of a link to the thread that contains the link to the song, maybe a link to the song itself would be more user friendly; clicking a thread, then backing up to the original post with the actual song link can be tedious.
Example- a thread four pages long won't show the original link if the thread opens on page 4, so the user has to go back through the thread looking for the link. The longer this waits to change, the more work it'll be later.
Just an idea.
