Ah, the long Memorial Day Holiday weekend chart-guessing game is upon us! There are a few moves that are easy to predict and others, not so much! Sam Smith & Normani's "Dancing With A Stranger" (RCA-Capitol) should stay #1 another week, but Jonas Brothers' "Sucker" (Republic) is looking to jump up for another week in that spot. Lil Nas X's "Old Town Road" (Columbia) and Khalid's "Talk" (RCA) move up inside the Top 10, while Ed Sheeran & Justin Bieber's "I Don't Care," joins it. Halsey's "Nightmare" (Capitol) comes screaming up the chart, landing inside the Top 20. Halsey will battle the newly-released 5 Seconds of Summer single "Easier" (Interscope) for Greatest Gainer this week.
