another thing is that it's become much easier for a popular artist's songs to chart high on the hot 100 since the streaming era started
if her songs get a lot of plays on spotify and youtube, then they'll chart. for songs to chart high before, people needed to buy them as singles or request them to be played on radio. now all they have to is stream them online, which changes the game
i don't care about that bunch of taylor swift fans went on spotify to listen to her album as soon as it dropped, "she made history" LOL no
