My current "soundtrack" is the most recent album by Mat Kearney. It's very light and summery... if you can describe music as a season. :-) But really, it's been on repeat and just always makes me happy! I imagine laying on the beach with the crashing of waves as the background to this album and I'd definitely recommend giving it a listen if you're a fan of light-hearted music with meaningful lyrics.
Hope you enjoy some Mat in your near future.
