Hi aldjano,
Probably the easiest way is to use Windows Explorer (assuming you are using Windows!)
If so, connect your Walkman to your computer.
Go to 'Start' and select 'Computer' or 'My Computer' (depends on which version of Windows you are using).
You should see a drive entitled 'Walkman' - double click this. You should then see a folder called 'Storage Media' - double click this one too and you will then be able to see all the folders stored on your Walkman. Songs will be stored in a folder called 'Music' where you just need to find the song in the album that you want to delete, and that should be it!
Hope that helps.
