The menu button

Question

well my menu button wont move left,right or down and i have no clue whether it will go up b/c that is the up volume and it is up all the way. so when i try to move from folder and song it wont move and i have to listen to it all the way through and i cant get out of a folder so i have to listen to the same songs over and over! idk whether it is just b/c i use it so much or what but it is really getting annoying!
any help!
