And in addition to all of the other awesome comments, let me give you some communications theory.

If a signal occupies K kHz of bandwidth,  you need at least 2K samples/second to capture the information in that signal.  This is called the Nyquist Sampling Theorem (it can be K  complex kilo-samples per second but let's not confuse you for the moment).

Hello Everyone ,

I am a GNU Radio beginner trying to implement Wideband FM Project and transmit it to my FM receiver at a very lower power.  I am choosing a frequency in a FM band such that my receiver is not picking anything from that station/..

Attached is GRC file which i am working on .and the music file which i am trying to transmit..

Can anyone please tell me where I am messing up ?

As a beginner , my learning curve is from implemented projects , University lectures which are available on-line .. This one is from a book which i am using to get basic understanding ..
