M.J. tunes

Hello my friends ........ I am new to this and there are somethings about it that I don't understand fully at this point ......... I have questions about it that I have asked some of the people who have "subscribed " to my list but no one answered .........
I get the impression that any time I recommend someone, the system wants to send this music to all of my facebook friends ........ Is that true ?.............. well that's fine , if I like the song ..........the problem is , at least with my present understanding , that the system seems to want me to "recommend" artists just because they recommend me ........... How can you honestly recommend songs that you don't personally like ? How can you send it to all your friends saying ........... wow , you gotta hear this ! ...... when you are honestly not impressed .......... a few songs sent out like that and nobody will care what I have to say ............ I want people to think that if I recommend a song , they are going to like it ............ they would soon get sick of listening to my recommendations if I was not honest and did not like the song myself ................ Suggestions? ....
I know there is some great music on N1M but it is not all great ......... of course it is just a matter of opinion .......... but should I not be true to myself and give my honest opinion ? Will someone please respond to this ? like I said before ...... Suggestions ?
