question:
What did Beyonce call her album that was not inspired by Jay Z or Prince?, Context: The feminism and female empowerment themes on Beyonce's second solo album B'Day were inspired by her role in Dreamgirls and by singer Josephine Baker. Beyonce paid homage to Baker by performing "Deja Vu" at the 2006 Fashion Rocks concert wearing Baker's trademark mini-hula skirt embellished with fake bananas. Beyonce's third solo album I Am... Sasha Fierce was inspired by Jay Z and especially by Etta James, whose "boldness" inspired Beyonce to explore other musical genres and styles. Her fourth solo album, 4, was inspired by Fela Kuti, 1990s R&B, Earth, Wind & Fire, DeBarge, Lionel Richie, Teena Marie with additional influences by The Jackson 5, New Edition, Adele, Florence and the Machine, and Prince.

question:
Why would it be best to use the USPS for packages here as opposed to another service?, Context: In 1899, the local postage stamps were overprinted "Guam" as was done for the other former Spanish colonies, but this was discontinued shortly thereafter and regular U.S. postage stamps have been used ever since. Because Guam is also part of the U.S. Postal System (postal abbreviation: GU, ZIP code range: 9691096932), mail to Guam from the U.S. mainland is considered domestic and no additional charges are required. Private shipping companies, such as FedEx, UPS, and DHL, however, have no obligation to do so, and do not regard Guam as domestic.
answer:
no obligation to do so, and do not regard Guam as domestic
