About that 'its not about being rich and glamorous' or that 'you should be thankful for what you have' ? Please! If you know any songs about it please let me know, thank you

Hi, I'm not really sure if these are the kind of songs you're looking for, but here goes :-
Where Do You Go To My Lovely by Peter Starsted
You're So Vain by Carly Simon
When I Was Your Man by Bruno Mars

Hope they're of some help :)

Be thankful for what you've got by William de Vaughn
