My mood board shows the stereotypical conventions of R'n'B:

• Expensive cars
• Make-up- Many girls are wearing alot of make up to portray themselves as glamourous
• High heels for the girls
• Seductive females wearing next to nothing
• Lots of money typically dollars as most R'n'B music videos are made in America
• Expensive houses
• Weapons such as guns to show crimes that may have been commited or being commited to get into this rich lifestyle "the American Dream"
• Men with youngers girls often more than one
• Dancing
