I've been tracking my music listening since long before Spotify via last.fm (formerly Audioscrobbler). I like the stats. I do use Spotify and it can be useful to find new music. I really don't know much by Taylor Swift though. She seems nice enough.
Have a rocking 2025.
I know she has a reputation and a lot of her songs have similar themes, but she really is a great writer and a pretty savvy business lady.
