I have recently purchased a sony usb flashdrive music player, i have looked at the technical details and it say's it will play Mp3 this good as i dont like their own music formatt and the annoying conversion program which is a pain and never shows all my music. 65GB of it anyway, most if all other makes of flashdrives you can get just drag and drop mp3's onto the stick but it wont recognise anything i do and there is no instructions on how to get it to play mp3's this is rather fustrating as i like the walkman it has a good build quality but i just want the simple option not their rubbish software or formats if anyone knows how to get this to work it be great to hear back
