Logo and Icon Design Project For Songwriting Website

This is what World of Songwriting was looking for in their logo design

I run a website called world-of-songwriting.com.
The website provides free songwriting tutorials teaching songwriters how to write, record and sell songs.
The music industry is a "cool" & "hip" place so I want the logo to represent that while at the same time looking professional and trustworthy.
The main colors should be grey and blue but I'm open to suggestions if they improve the design.
Also the logo needs to have a symbol which will stand on its on to represent my website. This icon will be used on twitter, Facebook etc.
Preferably the icon should be placed to the left of the world of songwriting.
Because world of songwriting is a pretty long title I think it works best if the words are stacked on top of each other in some way or another.
