"Keepin it Real" does it matter?

I think that as long as people make money from music the debate about "Keeping it real" will go on. But just what is keeping it real, and does it even matter? The Urban Dictionary says that keeping it real means "the act of being yourself". So when you hear a rock song on the radio ask your self if you think this band is staying true to their roots, or just doing something because they know that it will make them allot of money.
In alternative rock there are plenty of people that I think are sell outs and don't keep it real. The first band that I think of is Panic at the Disco. When i listen to their music I think to my self "there is no real meat in this song. Its kind of Pop and i don't feel like there is much emotion in this music." even though i feel like they are not "keeping it real" i still like some of their songs and don't really care. Which brings me back to my original question; does it matter if some one isn't "keeping it real?" To me it does not because I don't personally know an artist and its not like I'm going to start hanging out with them. the only thing that concerns me is the music, and if the music is still good then I will still listen to them.
Adam Scholey on The Daily Echo has a similar viewpoint about the band Nickleback. He said that the band had sold their souls to the Corps and started to sound "Pop". But he later went on to liking their new album. http://www.bournemouthecho.co.uk/news/blogs/3977217.Sell_Out_or_Rock_Out______Dark_Horse_Indeed_/

In conclusion the term "Keeping it real" to me is not a big deal as long as at the end of the day you still enjoy the music of your favorite band.
