Deleting all music off the sd

[gorelow]

Read all the threads on this still and it still doesnt help. Im trying to get rid of all the music on my sd card so i can put what i want on there. When i go to total commander in music it only shows the songs i like but when i go to media player and click on all music it shows hundreds of songs im trying to get rid of. How can this be? And i did a properties search and it says those songs are in the same folder
