I am no longer actively developing GetCDDB due to the lack of time that I can spend with my Amiga :( I *am* still supporting it though so if you have any problems please feel free to contact me. The source is released on Aminet /dev/basic/GetCDDB_src.lha
For the latest download, see Aminet.
Known problems:
Seems to fail on CD singles. Please tell me if your single was OK!
If you program in Blitz Basic and use the bsdsocket.library (ie Internet functions) then you need this archive. It solves problems with the way Blitz opens the bsdsocket.library.
