I really like Marina! I discovered Electra Heart at the end of 2012 and I've been listening to it for quite some time now and some of her songs have a great melody! It ended up to a point where I created a playlist on iTunes called Larina (Lana+Marina, lmao). Anyway, my favorite songs by her are:
Homewrecker
The State of Dreaming
Power and Control
Teen Idle
Valley of the Dolls
Sex Yeah
Oh, and when I found out she was coming to a location near me I decided to look up the date in case I could go to the show. I was already thinking how awesome 2013 would be since I'm going to see Lana in April. Well imagine my surprise when I found out that she was coming the exact same date and time of the year as Lana was... I just... fml
By the way, for all you Lana/Marina fans, there's a really good mashup I found on YouTube by accident. It's a mix of National Anthem + Bubblegum Bitch, I'll put it down in the spoiler
