Ok well the radio in my car has a usb port and i use it to listen to music off my flashdrive and i have recently put 1 song on my phone ( I do not have a memory card) just to test it and i pluged my phone in and selected hardrive sync ( not exactley sure if thats what its called) i was wondering if thats what im supposed to select , i used mixzing as suggested by google and it succesfully plays the song but keeps so memory card not available and i cant just clear that where i am able to select my music, is there a better app for just simply listening to the music i put on my phone, should i just use a file manager? or is there a way i can just manually find the music in my phone and select it? thanks in advance
