"Brainwashed" is a song by English rapper Devlin which features vocals from Milena Sanchez. The song, co-written by Pontus Hjelm and Emeli Sandé served as the lead single for the rapper's debut album, Bud, Sweat and Beers (2010). The track was first released as a digital download on 8 August 2010 having been added to BBC Radio 1's B Playlist the previous month.

Fraser McAlpine of BBC Chart Blog gave the song a positive review stating:

Honestly, some people can be so NEEDY.

I mean sure, if you're going to be a pop star, it helps to have the kind of self-regard which occasionally finds you checking out your reflection in the taps on the sink. But to actually BEG your audience to remember who you are – even to go to the lengths of spelling out your name* – and then brag that anyone who does actually bother to do this is clearly being brainwashed by your astonishing talent...

Well that doesn't just take the cake. That takes the cake, the cake-dish, the cake-slice, the table-cloth AND the pretty little seaside teashop. .^[1]
