I am planing to release a piano - CD in download stores ( iTunes and others ) with coversongs which are not public domain. To name it some jazzstandards

I have contacted SUISA the pro - organisation of Switzerland to ask about the copyright regulations in such case. They told me that copyright fees get collected automaticly in download stores and it is not nessessary to do anything special in such case. For me this sounds too good to be true

Maybe some of you has got some experience on this topic and can convice me that it is in fact the way SUISA told me.
Thanks for you help in forward
