Button stuck on home/back-Button disconnnect?

(edited/updated)
So my home/back button was stuck and I thought it was because maybe it was stuck down by debris or something, but I took it apart and even when the whole thing looks normal, whenever I try to play the music it goes straight back to the menu as if the home/back button is still stuck down. I'm assuming this is some kind of circuit problem because the whole thing's been taken apart and the button isn't being held down by anything... so does anyone have any suggestions on whether I should/could disable the button altogether? I wouldn't be able to press it but I reckon I can live without the function if I just turn it off and on again to get to the home screen.

Thanks!
