My personal compositions belong to me, but I defend culture free circulation.
Therefore my pieces may be played, interpreted, modified as much as you want. You might, if you wish, take only the music or the lyrics. You may play them publicly or only for your mum…
The only condition is to attribute them to their author by citing my name: Rex Potam.
Derived pieces must be publicly available under the same conditions as the original pieces.
The full license is available here.
Oviously, the works I compose for other people are not free.
