I don't know if this is a problem with using double twist to sync music then the default player to play it, but i recently wiped all my phones music useing double twist media sync program and then put some more music on... after this i went into the default music player and it was very lagy and showed songs that i had removed with double twist but when i went to play them it would play a random song that was on the phone... does anyone know how to get the media player on droid x to rescan your sd card so i can realize that some songs are gone now?
