For us, the system lost popularity because over the few years the DLF and WDWF systems were open we had bought about 2 dozen CDs,I've heard a rumor going around that WDWF may come around again in the near future. I have no clue how valid it is, but we can at least hope.
I'm afraid that WDWF closed not totally due to RedDotNet, but mainly because people downloaded all of the songs online. It's really a shame. Both WDWF and DLF lost popularity, and therefore, we lost them.
Hopefully the new CDs won't allow computer transfer...if they ever come out... :'(
