Is there an app on xbox 360 where i can download just tracks not music videos
The Xbox 360 does not have any download apps. If you need to download anything, you will have to go to Xbox Live. Xbox 360 only allows you to play the downloaded games or music.
maybe not sure
You have to create your own network with a router wireless network card and ethernet cable and then connect your PC to your Xbox and listen music there with media center app
