I bought some blank CD's that were 80 min long and they were CD-R. So, I tried to burn onto them and it would only let me burn like 6 songs. It never said how many MB it has but I know it probably holds about 700 MB. But there's no way 6 songs were 80 min or 700 MB. On the package, it says, "For WALKMAN use" Does anyone know what that is? Yeah, and I want to know what CD-R means and if it makes a difference to how many songs I can put on the discs. Thanks!!!! <3 <3 <3 <3
