There are not a lot of things to think about, but just a few landmarks to be aware of =)

I have all rights to the songs that I write, pretty fucking simple!!

Public use
People are free to listen to my songs (for private use), when on a party etc.

If someone would like to use the song, make a cover or use my lyrics/music for something, they need to contact me about it.

In short terms, any use that couldn't possible give someone money is a free use =)

Anyone can download my music to save it on their machine (PC, phone, mp3-player etc.

Anyone can share my music to a third part.

Aaaaand I think that will be it. Simple and clean!
