Iam using foobar and iam very happy with it. But there seems to be a bug in the albumart component.
It's not a bug, just not the behavior you're expecting. Invalid filename characters in tags (such as ':' and '/') are replaced with the wildcard '?' before any other titleformatting functions (such as $replace) are evaluated. That means you can't define exactly how invalid characters are replaced.
what is the correct string for albumart to display it?
The point is, you have to replace the ":" with another character in the filename. As far as I know, there is no way to make it work with the colon removed.
Big thx. finaly working. I didn't thought about replacing with another legit character.
