Ever since my older sister gave me GROUPLOVE's album Never Trust a Happy Song for Christmas, I've been in love with their unique sound. It's kind of hard to pin point their style (Wikipedia says Indie or Alt Rock), but when I listen to their songs, I think of summer, friendship, and pretty much awesomeness in general. Plus, the only girl in the band, Hannah, has incredible style.
Their catchy single "Tongue Tied" has been really popular lately (my dad even hums to the tune), but one of my favorite songs is "Naked Kids". There's no music video, but enjoy this lovely song.
