(Girls) Send the lyrics to this song to the girl I wanna ask out?

wait, SHE told YOU to listen to the song? If that's the case then she's obviously trying to tell you that she wants to be with you so just ask her out. Don't ask her out in a text, that's lame. If you really like her show it, and take her someplace nice, or do something cute, then ask her out. Ask her out in a way so that she'll never forget it.
