Taylor's latest single, "Delicate" just went #1 on Pop Radio after already spending 19 weeks on the chart. Truly a sleeper hit. Therefore, i thought I'd take a look back at the era on Pop Radio. This is for POP RADIO and not the Billboard Hot 100.  The chart keeps track of the 40 most played songs on pop radio each week. Songs are knocked off the chart if they have been on it for 20 weeks and can't place in the Top 20, after that. (songs typically stop getting played a lot after that point
