When i delete music of of my muve music app, the songs still stay on my sd card. Rite now i have 427 songs on the app but i cant add anymore because there are 3000 songs clogging my sd card. How do i get all of that clutter off my sd. I would really hate to delete the card and reload the music on the app because that would involve about 4 hours of redownloading. Any tips???
