Sure, we all buy copies of the albums, but casual fans might not if she releases 3+ singles before the album comes out. Just doesn't seem like a good plan to me.
I don't like the idea either. I really like holding that cd in my hot little hands!!!!
3 singles is too much but a lead single and a second single just in time to the album release week to add excitment is an amazing idea, plus she can perform both songs in all the TV shows and not just the lead single over and over again.
Plus she released 3 promo singles before the album drop with Play On (Undo It, Temporary Home and Mama's Song) and I think she did the same thing with BA. So people will buy the albums even if they already have 3 o 4 songs.
She should have released Heartbeat before the album release and ST could have sold much more.
