(SPOILER ALERT:) I decided to use the best-selling/highest-charting singles for each of her three albums, as far as I could estimate by comparing multiple markets, as well as the best-selling/highest-charting non-single off the first two. I didn't use a non-single from BTW because the album hasn't been out that long, so the songs haven't had as much time to chart and some of the non-singles will certainly become singles in the future.
I hope I gave about the right amount of time - not too much but not too little - but I'm not too sure of myself about it. |
