this is probably so vague, and i doubt anyone can help (but hey worth a shot) but i was in an AE early july maybe, and there was this song that kept saying "i will let you down" during the chorus. of course upon googling all i get is hurt, but regardless that's all i could remember. i was trying to shazaam and nothing! it kind of sounded like two door cinema club which i thought was a possibility but after youtubing them to hell and back couldn't find anything. had a very undercover martyn, i can talk kind of feel to it. i just remember hearing it and being all THIS IS SO GOOD and i asked the one dude and he just shrugged. yeah i've literally been looking since early july oh well
