SS 3.4 even allows you to upload to multiple computers.
For example, I can take tunes I digitally recorded from an optical, digital or analog input (and mic input) source:
1. Upload to as many computers as I want
2. Upload, convert to WAV or ATRAC, transfer back to the MD and then transfer again to a different computer
3. Can also rip CDs to MD on 1 PC and then transfer to another computer.
As long as you tell SS 3.4 not to use DRM restrictions on your tunes, you will have no problems with restrictions for uploading, downloading or transferring. It's really the best SS yet.
I have enjoyed loading tunes from my home PC and finally being able to transfer them to my work PC and play using Winamp while at work instead of having to keep my MD player at work all the time.
