There are tons of Add-ons for Kodi I am only listing the ones that I use and like and know that work. Feel free to browse and install anything you find on the add-ons page if you'd like.
To install the add-ons that will allow you to stream movies, tv and music follow these directions:
Click On:
System>>>Settings>>>>Add-Ons>>>Get Add-ons>>SuperRepo>>>Video Add-Ons
Then Search for these click on them and select Install:
1. Genesis
2. 1Channel
3. Project Free TV
4. DIY
5. HGTV
6. Food Network
7. Vevo TV
8. Phoenix
They will then appear on your home menu screen under Videos>>>Add-Ons
