When I got this CD Single in the mail, I could not wait to open it! I have listened to it so many times and to say it's WONDERFUL is an understatement. The only reason I got this was so I could listen to the song titled "Deep In My Heart." That is my favorite song that Britney has ever recorded. It is so good and so unlike any of her other songs. The money is well worth it just to get that song! "Oops I Did It Again" is awesome, as you all know. The instrumental is the exact same as the Album version, just without the voices. It's nice because you can pretend like you are Britney and sing along solo! "From The Bottom Of My Broken Heart Remix" is okay. I'm not too fond of that song anyway, but it's much better than her Baby One More Time version. Overall, this CD is great and a must-have for ANY Britney fan!
