Hello y'all!
I have a huge collection of (*.SID) tracks but i've noticed that the file format is unsopported. My sugestion for a huge step is to make this possible so i can rename my files accordingly! 
You guys rock!
Cheers!
The support of the format by Mp3tag was already asked by me more than a year ago (in Oct. 2006) in the german suggestion forum (to read it, klick HERE).
This is what Florian answered these days:
But anyway I'd also agree it, if the SID-format would be supported by Mp3tag one day.
Hello again!
I apologize for the late reply. I'd be extremelly thankful if this upgrade would be taken in consideration by the DEVs since i've not found a "tag tool" for this specific file format. Plus, after getting me hooked to mp3tag i simply refuse to take this painful task by hand! 
I appreciate still for all the efforts taken so far with mp3tag!
Take care!
