If taylor wanted to tie katy's record she would do it easily if she wanted, she has songs as generic/safe as the ones Katy released from TD and Taylor's actually have quality
Now that Apple Music free trial is ending for most people and many won't subscribe, they are now forced to buy Taylor's songs seeing as she doesn't have music on spotify
Apple Music is awful and no one will use it. Taylor needs to go back to spotify otherwise she will struggle next year with chart positions (like she is doing in the UK/Europe already). Digital sales are over.
