Lonely Hearts Club

So this song is part of the Electra Heart album (the deluxe version I believe) so Marina obviously meant for this song to be relevant to Electra's life. Just as a heads up, this will be a long explanation because I'm going to try to break apart several aspects of the song so people can understand it better.

For anyone who is not familiar with the character of Electra Heart, she is the antithesis of Marina and people in general for the most part. She's shallow, annoying, and lacks identity. Trying to compensate for having absolutely no personality whatever, Electra goes around "stealing" identities, ranging from a housewife to a beauty queen to a homewrecker to an idle teen. Now that you have an idea about who Electra is, it makes understanding this song and pretty much every song on the album much easier.

Lonely Hearts Club is pretty straight-forward: Electra Heart is in fact quite heart broken. She feels that no one wants to be with her (which in her case is actually probably with the way she acts). Because she's so alone, she wants people to unite with her to form a "Lonely Hearts Club", possibly even going so far as to trying to find love inside her new club since 'lonely hearts' gives off a sense of desperation; the members of the club are so alone or feel so alone that they will do anything to change that.

Now moving onto specific lyrics:

Laugh track on a TV show echoes in the dark alone I go to bed feeling bad that I’m the reason that you’re sad

Electra has yet again run away from a relationship since she's proven in "How To Be a Heartbreaker" that she's about as good with relationships as a fish is surviving above water. She's sitting in a dark room with a TV show laugh track resounding through the silence. It's possible that she's even watching a comedy to try to make herself laugh; she realizes that jumping out of the relationship was a bad idea and she feels bad for making her ex sad, but she doesn't do anything to change it because she'd first have to admit that there was something wrong with her.

January to December, do you wanna be a member?

Electra is very obviously full of herself. She's making a club of lonely people specifically to make herself feel better. Therefore, if someone joins the club, they will most likely be signing a contract for a full time commitment of being Electra's personal assistant or comforter in some way.

Lonely hearts club Do you want to be with somebody like me?

Again, Electra is quite possibly using her Lonely Hearts Club to try and find a new 'love', although due to her history, it would end as soon as she developed real feelings and she'd wind up right back into her club.

I feel like if I’m too kind then you will only change your mind

This shows just one of Electra's identities, the beauty queen or, as one of her songs states, a "Primadonna". Primadonnas act how they want and most often act arrogantly because no one tells them know. They take what they want when they want it and are very shallow because they are (or at least think they are) the best so that means they're automatically entitled to anything and everything. Electra is actually revealing a fear of hers here, which is that if she acts sincerely nice, her love interest will lose interest in her and leave. This, in Electra's mind, serves as her justification for acting like a Primadonna.

Take advantage of my heart and I’ll go back into the dark

Furthermore, she goes on to say that if she feels that if someone is "taking advantage of her heart", she'll just run away. It is probable that Electra does this as well if her lover is the perfect boyfriend and has just begun to make Electra feel genuine happiness. Again, she's so consumed by fear of being hut that she thinks everyone is out to get her and hurt her so she constantly runs away.

Love will never be forever, feelings are just like the weather

Because she's godawful at relationships and ends them before they begin, she doesn't know what a real one is actually like. She dumps a guy quickly and probably has even brainwashed herself into thinking that she's just lost interest in him rather than her being scared of being heartbroken.
