You might also give Flashnote a try since it does the same job. Press a hotkey, type incoherent content if you like, press the hotkey again and you're done - the input windows appears and disappears on demand. Whenever you like, you can later transfer things as needed to somewhere else. Flashnote is not a notetaking app.
You might think of it as an incoming bin / thought repository that's instantly available via a hotkey press. And since the cursor will be already positioned at the end of the document (if that's how you want it), all you do is get a thought, press hotkey, type, press hotkey again to close the window.
I find it helpful sometimes to tag input so that if it's very important *** , string like *** might appear (priority rating), etc. ((topic 1)) might refer to a particular topic.
This type of tagging, along with other tags could allow you to consider everything useless unless it's tagged. I only need a fraction of what I come up with, but it's nice to have a no-friction way to capture any thought instantly without interrupting your current task.

You might try using Flashnote. Press a hotkey, type something and press the same hotkey to close it. It's invisible until you open it
Just this morning I've jotted down several things to do and ideas. You don't even have to look when you type something. You may want to press Enter before closing the window so the next time Flashnote opens, it's on the next empty line.
Later you can do whatever you want with what you've written. A text expander can help you insert a timestamp with each entry. Adding tags can tag things you write.
What you typed as an example, ie "Black Sabbath - Into the Void" is kind of how I input things in brief form. I know what my input means even if it's very short like your example. Comma delimiters might help if you choose to put multiple thoughts on one line.
The great thing about this is you can input many many many random ideas, tasks and thoughts throughout the day without interrupting your current workflow. And in your instance, you may in a way explore a random interruption without stopping what you're doing because .. you'll capture the thought in a safe place where you're free to explore it later.
Flashnote is not a notetaking app. It's one job is to help us instantly log ideas without interrupting our current workflow.
Recording time is limited so I have to create multiple recordings as needed.

Single Page
In OneNote you can create a Table of Contents / Index / Topics page that contains links to categories such as Shopping and Tasks. That way you could always visit that page and click a link to go to a specific category where you can view it's information and add new content.

Rapid Information Capture
For rapid information I often use Flashnote.

I can press a hotkey, type something and press the same hotkey again and I'm done. I don't even have to look at what I'm doing. Later I can move what I've typed to another program.
As an example ... ... I just opened Flashnote, typed something and returned to this sentence without thinking about it. I didn't lose my focus on this paragraph. What I typed into Flashnote gets appended to the end of the file and later I can move things I've I typed somewhere else.
This process is similar to having an incoming basket on a desk and putting things there quickly. Later you can move them to their ultimate destinations. You could probably do the same thing by keeping a particular OneNote page, perhaps named "Incoming" always open on your task bar. You could click it, type something in it and close it. But I'm not sure if that would be faster than using Flashnote for rapid initial information capture.
