Feeling Alejandro

I think you guys can tell I haven't been exactly cheerful lately.

I really liked this song when the video first came out, but I feel the elements of the song so much more now. Guess you need to be in a dark place to truly appreciate it.

The message is not entirely clear, but I think that's part of the idea. To make it more intriguing, get people talking, keep fans guessing. It would be less effective if it were blatant.
Watching the video makes it more confusing. Which part is truly conveying the message, which part is just meant for cinematography, and which part is just for publicity (dressing as a nun)?

The first impression I got when I heard the lyrics was... Gaga having an affair with a married man, or someone who's clearly taken, so Gaga knows she has to let go. The line "she's got a halo round her finger, around you", the halo described should be a wedding ring, one that the man is wearing and so is his wife- hence making Gaga the third person.

More interesting (and controversial) theories I have read claim that Alejandro signifies God. The scene where she lies in bed dressed as a nun, she looks up to the sky when she said "Stop, please, just let me go, Alejandro". She raised both hands up when she called Alejandro. Several other signs in the video were reported as Gaga rejecting god, opting to empower herself instead.
Gaga fans out there please read this with an open mind, everyone has an opinion so I guess we should at least listen regardless if it's right or wrong, as long as you know your stand on it.

Personally I think the whole religion thing is just a publicity stunt, don't think she really is out to control everyone. But if you think about it, her meteoric rise to fame and how her fan base is growing in such a short period of time does make me wonder how or why it happened. It's not exactly normal.

Back to the song. Basically the theme is rejection. Doesn't matter if it was a break up, or if someone died, or if they were forced apart, it all comes to the same ending: loss of love.
I read a MTV interview where the director of the video said it was about "The pain of not being with your true love".
