SanDisk Developing 128 GB Micro-SD!!!!

You can use it depending on what quality levels you’ve chosen. God forbid you listen to only 2,000 songs instead of 40,000. I can’t imagine how long it must take you to even approach listening to 500 songs in a row, and if you aren’t listening to it all at once then you’ve got little reason to complain - go back to your computer and reload it with the songs you didn’t add, or replace the songs you aren’t as fond of in the player.
