Hi my friend,
First download all these files to your PC. Next, Google search for "Winzip", "Winrar" or "7zip". All of these have versions that are for free. Then install on your PC. Once done, right click on any of my files & select "extract to" and select a temporary directory on your PC.
When done, go to the "user styles" of your Audya. Create a new directory called "Extra Styles" and copy & paste all your new styles over there. You can keep the folders of these styles and rather copy the complete different style folders into the "Extra styles" folder on your Audya. Do not copy into the existing style genre folders as there are more than or close to 50 000 new styles. Rather keep them separate in your "Extra styles" folder.
To access these new styles from your Audya, use the "Disk" function and browse to the relevant folder. Highlight a style & press OK. Now you can play the style as normal.
All the best mate,
Make sure you'll fly forever!
