This one's quite poppy, but it reminds me a whole lot of Portugal. The Man, so I reckon it deserves a shout here.
"Left Behind The Gold" features a modern hip-hop singer by the name of TxTHEWAY. He's all about that autotune sound I normally can't stand, but it works so darn well with CARDS' indie rock sound that I just can't help but listen to this on repeat.
