@mgafner Necessary in 0.2.0?
I'd like to tag 0.2.0, that I can proceed for debian release.

Question is: do we write the id3tags exactly as they come from the radio station or do we change the case to a predefined format.

I propose the camelcase format. But we can make it configurable too.

let's plan it for the next release.
