Hey! I've just got a NWA1200 & am importing all my CDs to My Library using SonicSatge v4.3. My b/f also has one and he says the file size for each track I've imported compared to his is really big e.g. over 10MB for 4m30s. I've imported them in the ATRAC format at 320kbps and approx 440 CDs and have used just under 40GB... Is this good? I'm worried that when I transfer them to my Walkman I won't be able to get on as much as I'd like. Help, please. I really am useless when it comes to things like this! Thanks!!!!!
