An incredibly underrated musician that released three sad and beautiful albums before committing suicide. His final album, sarcastically titled "It's a Wonderful Life" was his best and is a classic, or at least it should be. The best songs on that album are the first three: It's A Wonderful Life, Gold Day, and Piano Fire.
Check Sparklehorse out on youtube his songs are really sugary sweet and melodic while also being kind of sad. It's a great combination you'd probably like him
