To anyone asking for this to go to Geometry Dash, it can't. A while back Robert and Newgrounds stopped new artists on Newgrounds from being able to upload songs, so only artists that made their account before that can upload songs and use them in Geometry Dash now.

If you're on computer, download this, and find a way to get a "custom custom song" for your computer. For example, of you're on windows, like me, or on mac you can just do what i list below:

Find the ID of the song, Crystal Corruption, Magic Touch, Faded, Etc.
I'll use crystal corruption just since this is the actual song i'm posting it on soooo.
The ID of the one before it was taken down is 699671, you'll want to keep that in mind later.
For Windows, search for this: C:\Users\(YourWindowsName)\AppData\Local\GeometryDash\
Replace the ()s with the name of your account for the computer. Example, if it is called Bob, it would be like so:
C:\Users\Bob\AppData\Local\GeometryDash\

If you're on Mac, go to ~/Library/Caches/.

Now, the process here is pretty similar, now that you've downloaded This song, (If you haven't you should!) Go ahead and rename the file to the ID i mentioned earlier, 699671.
For Windows you now want to go into resources and after you have renamed the file go ahead and put the file into resources and the song is now installed.

For mac, if you already have a ton of Songs downloaded for geometry dash, you should see a bunch of files.

For example:

199132.mp3
217344.mp3
619221.mp3
and etc.
Go ahead and take this song file, make sure you renamed it to the ID of the song, and put it into there. Now when you go back into GD, it will allow you to use it.
