You asked about the chart. Songs are released at the same time, but they have an "IMPACT date" for the chart. For example, The Kid Laroi's new song has an impact date of Feb 7. However, hundreds of Top 40 stations are playing the song already. It's even charted at #24, so we know it's getting a lot of airplay. It will take time for it to go from #24, where it may be getting 15 or so spins a week, to #1, where it will get over 100 spins a week. But then again, we're talking about a local radio station, not a national music service.
