According to Comic Book, the journal is shown in the first few minutes of Captain America: The Winter Soldier. The footage has been previewed in advance of the film's premiere (it's 3/26 for some of the world and 4/4 for the United States). They explain:
Steve Rogers (Captain America) meets Sam Wilson, who suggests he listen to a Marvin Gaye album, to help get him caught up with the decades he lost while frozen in the ice between World War II and the start of Marvel’s The Avengers.It's a small touch, but I love that Marvel included it in the film, and that we get to see how Cap is trying to become accustomed to living in modern times. Since Star Wars appeared to be crossed off the list, I'm dying to know what he thinks about it.
