Tom, what do you use for terminal?
Oh, beautiful. I downloaded the tar.gz and then checked the repository and it was a .deb. It opened up into the folder where I have the music. Now I just need to learn the keystrokes and I'm good. This looks perfect. Thanks Tom!
I found this helpful page on the basics of running it. The cmus tutorial was a bit overwhelming, but this got me going and understanding enough to enjoy it.
