it has loaded music before and now it isnt and i dont understand it and all the files are the same, and is there a way to load more bass on an mp3 player

Sorry could you make the problem more clear?,
Sometimes MP3 players can be funny if they have a variable format meaning if they bounce from 128kbps-320kbps.
I recommend you use some thing like NCH Swift Audio converter to keep them at one varible and try again.

A friend of mine managed to delete the music folder from her computer. Until she restored this folder she was unable to transfer anything to the player. Perhaps you have accidentally messed up your player.

Depending the the type of mp3 player, but there should be an option to allow you to reset the device. It might help, if not it might be the mp3 problem. Either that or there something wrong with the connect from your mp3 player to the computer (vice versa). You could also try connecting it to another computer to check.
