I am currently about to launch a site of mine which is for VOIP phone reviews. I thought of a cool name however I have recently found out that the site name is also the name of a song released in 1963 by BMI.

Not only does my site name have the same of the song, but the name of my site is all the words in the chorus of the song. The song is about "calling someone".

What are the potential legal issues with this?

Is the topic of viop phones too similar to the song topic of calling someone?

Can you even copyright/trademark/whatever a song name?
