It's not as easy as you think, says Swiss photographer Roger Eberhard, who's visited hotel rooms in 32 countries and six continents for a project exploring standardization in our major cities.

In his aptly titled book "Standard," Eberhard photographs Hilton hotel's entry-level double rooms at the same angle in several global cities -- from Sydney and Tokyo to Addis Ababa and Panama City -- alongside snapshots of the world outside the hotel window.

The heirs of songwriter Ed Townsend have sued Sheeran in New York federal court for copyright infringement of the 1973 soul hit "Let's Get It On." Townsend and Marvin Gaye co-wrote the song.

"The Defendants copied the 'heart' of 'Let's' and repeated it continuously throughout 'Thinking,'" the lawsuit claims. It alleges there are "melodic, harmonic, and rhythmic compositions" in the two songs that are "substantially and/or strikingly similar."

Gaye died in 1984 and Townsend died in 2003.
