Spain’s indie scene doesn’t so much embrace a specific sound as it does an attitude: No matter the genre, these innovative artists present a defiantly left-of-center take on tradition. This playlist collects future hits and unsung gems from across the spectrum, whether moody and low-key rockers, anthemic party-starters, or something comfortably in between. We regularly add new music to this set, so if you like a song, add it to your library.
