hi there gurdy!
Sony mp3 players are great mp3 players, except with one problem. You need to get Sonicstage, the mother program for their mp3 player, to put music in their. So, one way is to go here first:
download the Sonicstage program, and install it into your computer. (WARNING! First install the Sonicstage, then connect the mp3 player to the computer, otherwise it might not work.)
When you are done installing it, and you plugged the mp3 player, open up Sonicstage. It should open up with a screen saying many things such as My Library, Transfer, Music...
From there, go to add music (top left corner button next to My Library, next to it) and three choices should come out, saying add files, add folder, or import CD. From there just add files from your computer.
Then, click the Transfer button. There you should have a split screen, half My library half Transfer aka mp3 player space. Choose the songs you want to import and click the arrow pointing right (in the middle).
Give it a few minutes to download into the mp3 player.
After it is all done, either exit the program or just pull out the mp3 player and wha la music to your ears!
It's a nice mp3 player.
Hopefully this solution helped out.
Please contact or reply if you have anymore problems.
this is where you can read the manual and all the information about it.
