Lady Gaga sugests this in 'Born this way'
e.g. the following lines
‘There’s nothing wrong with loving who you are’
‘Hold your head up and you’ll go far’
‘I’m beautiful in my own way’
‘I was born this way’
and
‘Don’t hide yourself in regret just be yourself and you’re set’
In 'Undiscovered', James Morrison sings the following:
'Im not lost, not lost, just undiscovered
we're never alone were all the same as each other
you see the look thats on my face, you might think that i'm out of place
i'm not lost, no no, just undiscovered'
This relates to identity in a different way as it infers that we are all always changing who we are and trying to discover 'the self'
