Is there a way I can have a thread not terminate?
I want the audio player of WhiteBird to have its own thread, so it can run (and crash) independently of WhiteBird. So I create a new thread for it, simple. The problem is that once the thread does one thing it terminates. I need the thread to say play music, then wait around for something to do (like the thread pool). I don't want to use the thread pool simply because it is performing other tasks (navigating web pages, i/o, etc.).

Presumably you're calling some thread exit code then, no?

No, all I do is call .
It does what it needs to then the thread terminates.

My advice then is to read the documentation on the thread type you're using. It seems to me that the method does most of the work for you (not trying to suggest you're in some way lacking), so when you start it up it does its thing then goes, and you're not being given much choice over how to do it. So, see if the docs tell you how to stop that/do it properly.

Now I am confused, everybody (msn, codeproject, c-sharpcorner, etc.) tell you how to start a thread, lock, pulse, suspend, abort, etc. but they do not tell you why a thread closes automatically.
Here is some sample code that I had:
code Thread tNavigate = new Thread(new ThreadStart(Navigate)); private void Navigate() { WebBrowser thiswebbrowser = GetCurrentWebBrowser(); thiswebbrowser.Navigate(TSCBurl.Text); } Whoops!
This is what I get:

Fancy posting form.cs? I don't know enough about your implementation to say whether it's thread safe of even sensible yet! How much have you looked at threading?

I've look at like 12-15 documents, and they all say do it like that.

Your thread is exiting because it is reaching the end of your function Navigate().
If you don't want it to exit then it needs to loop forever instead. Of course that is a good way to use 100% of your CPU unless you have it sleep and/or poll for events as it loops.
Really you shouldn't be messing with threads at all, I think. Threads are extremely difficult and not necessary. I wouldn't recommend threads to anyone but seasoned pros, and even then they should only be used when there's a really good reason.
You need to learn and truly understand concurrency, race conditions, critical sections, semaphores, resource deadlock, volatile memory and a swarm of other highly advanced topics before you can safely use threads. And I'm sure you have plenty of more important things to try and learn first; things that this thread stuff is dependent on anyway.
