Okay, I have a great playlist of true Hawaiian music by Hawaiian Artist...
Check these out!
Ka'ena Dream by Makana (love this one)
Ka Uluwehi O ke Kau by Hapa
Backyard Slack Hawaiian slack-key guitar ukulele by Sean Na'auao
Ulili E by Dennis and David Kamakahi (from The Descendants)
Dukes on Sunday by Henry Kapono
Ipo Lei Momi by Keali'i Reichel
Koke'e by Ledward Ka''apana "uncle Led..."
E Nihi Ka Hele another one by Makana (more Hawaiian slack-key)
These are from a couple years ago, and there might be more current songs by Hawaiian Artist.
