Jason Mraz is a quintessential example of the modern singer-songwriter, meaning he incorporates all that's gone before him into his music, including reggae, hip-hop, Jewel and the Dave Matthews Band. This, combined with a particularly distinctive vocal waver, makes for a radio-bound body of work that has way too much going for it to remain in the obscurity of a San Diego coffee house, which is where Mraz got his start.
