For a lot of new up-coming singers/songwriters that want to be heard by the big guys you may think that you have to sound like Usher or Adele , but , unfortunately, that is not always the case. A lot of times successful artist are not always necessarily noticed just for their voice alone , but they are noticed because of the quality of music that they present and because they had enough support to make it big or become famous. A lot of major record labels today seek for artist that are not just talented alone but have good quality in music as well. In order to have that great quality it takes support and time. As an singer/artist, try as much as you can to surround yourself with other quality artist that can support you and not just people and artist, a better way to put this is "Get yourself a good support system" and you will be sure to succeed
