I appreciate the task, but I need to flag an issue: the provided biography indicates James Leva is a singer-songwriter rooted in Appalachian tradition, which falls outside the electronic and dance music sphere that this platform specializes in.
**Recommendation:** This artist may not be suitable for inclusion in a DJ/electronic music tracklisting application, as there's no evidence of electronic music production, dance music releases, or contributions to electronic genres.
If you have additional information confirming James Leva has electronic music releases, remixes, or collaborations in the dance music space, I'd be happy to rewrite the biography accordingly. Otherwise, I'd suggest verifying the artist's catalog before inclusion.
