I HAVE CONNETED MY PS3 TO MY COMPUTER VIA WINDOWS

Yeah I know its a pain... I tried to do it that way too, I ended up calling Sony themselves and this is how they told me to do it. You have to put it on a flashdrive or some other removeable staorage device w USB. Step1- Get a flash drive, stick it in a USB port on your computer. Step2- Go to your music files, like where they are listed on the HD, not WMP. Step3- Highlight a song and rightclick on it, there a bunch of options will pop up. You want -SEND TO- And as you hightlight that at the bottom it should say REMOVEABLE DISK.. Go through and put all songs on the flashdrive this way.. If you hold CTRL down on your keyboard you can go through and select them all at the same time. After youve gotten all the music off stick flash in the PS3.. Go to your music tab and USB should be listed.. Hit triangle on it and go to display all It should all be listed there permitting the PS3 supports all the file types. Go to the first song, and hit triangle on it. It will give you the copy/delete options.. At the very top you will see copy multiple. Click on it and you can go through and copy all songs at once. After that, you should be smooth sailing.. If you need to delete the flash drive to get more music you can do it by Putting it back in the computer and going into MY COMPUTER.. It will be listed under removeable media. If you click on it it will give you the options to format or you can just right click on everything and select delete. good luck.
