No, not magically. Organically, because its logical.

Usually I might post to that thread if I like a particular track but don't like a whole album or if I want to quickly share a track and get back to work :).

Honestly I hardly ever bother with them. I prefer the genre recommendations threads because they are great ways to find new music rather than just a random what are you listening to post.

just because it's logical doesn't mean it's going to work in practice. The logic behind it is flawed.

These threads are quick dumping grounds if they aren't around, it's not going to force someone to create a worthwhile thread based off of one single track.

I think you're misinterpreting this intentionally. Rather than post in those threads you would either...

A. Post in the existing thread

B. Create a new thread for the act because one doesn't exist.

I'm not making the assumption that someone will go from Copy & Paste to thoughtful exploration, but in what I'm suggesting, Copy & Paste will lead to thoughtful discussion, albeit with another person leading the discussion.

Copy Paste into a thoughtful discussion can happen in the thread that already exists. It doesn't but it can it's open to that possibility. There are thoughtful discussions that happen in the Albums you are Digging Thread and the Last download thread not so much in what you are listening to but from time to time people will discuss a track. You don't go into those threads often so you don't see it.

If someone wanted to lead a discussion on a single track they can take it from the thread that already exists and open a new thread to talk more about it.

There is just no need to close down those threads that already exist.

Like I mentioned though, a few times I have been into the 'What are you listening to' threads and posted a comment about a song that someone was listening to, or tried to facilitate a discussion, and it is rare that anyone even replies! It's obvious that it's not a place where members want to have discussion, they'd rather do that in other threads (such as the What album are you digging or latest download thread...) While it does have potential, in reality it's not really happening even when members try to jazz it up a little more than just a YouTube link.

Having said that though I don't mind just ignoring that thread when it pops up in my new posts, I guess other people who post in there still enjoy just sharing a link to a YouTube video or posting a song title...

Like I just mentioned if you did want to continue that discussion all you had to do was copy paste that track that you wanted to talk about and make a new thread to start a discussion about it.

So now forum-first members have to do twice the work so that lazy people can just throw a video up without having to grunt?

I don't know, man. That sounds pretty ridiculous.

If they want to have a discussion some work is required.
