Republic Corps' Spangler & Lucas will kick off the July 4th holiday week with Sabrina Carpenter's "Espresso" (Island) as the new #1, while her latest single, "Please Please Please," is the Greatest Gainer and takes a huge jump up to join the Top 20. Debuting on the chart this week will be ICLG's Team Marella with Kendrick Lamar's "Not Like Us" (pgLang/Interscope) and RCA's Rothschild crew with Myles Smith's "Stargazing.”
