More power to Jay-Z and Beyonce

Jay-Z and Beyonce joined a list of top music executives, led by Live Nation Entertainment chairman Irving Azoff, on Billboard magazine\'s first Power 100 chart on Friday. The selection was determined by a combination of money, market share, Billboard chart data and other information, and a team of 15 magazine editors analysed the results to produce the list. Both Jay-Z and Beyonce made it due to numerous ventures outside their singing careers including Jay-Z\'s Roc Nation music, management and entertainment company and Beyonce\'s sponsorship deals with brands such as L\'Oreal. Collectively, they were placed at No 13 on the Power 100 list. Rock band U2 came in at No 27 and fellow rocker Jon Bon Jovi clocked in at No 50. Country music star Taylor Swift, 22, made the list at No 78 for being a \"branding powerhouse\" and Lady Gaga followed Swift at No 84, picked for the sway she holds.
