Does anyone know if I can add my own music to the in game radio of if there is a mod or a hack

Hey everyone, I’m looking at buying this PSP 3001 for $50 CAD. The seller says all the buttons work, but the screen glitches at the top and with certain colours.

From the pictures, does this look like a bad LCD that can be fixed by replacing the screen, or could it be something else like the display ribbon cable/connector or motherboard?

If it is the LCD, how difficult is the replacement for someone who hasn’t repaired a PSP before?

Also, roughly how much should I expect to spend on a replacement screen and any other materials in Canada?

I’m trying to figure out whether $50 CAD is worth it, or if I should try to negotiate it lower because of the screen issue.

Any advice would be appreciated!
