Hi Troy,
Learning the theory and the movements can be frustrating if you're not able to apply it to actual music.
1. If you want a bunch of beginner songs to use those new chords you're learning with, go here: https://www.guitartricks.com/songs.php?input=beginners
This is a list of a bunch of beginner songs for you to learn. Check it ou t!
2. I don't know of a tool that allows you to search for song lessons by chords either.
3. If you enjoy fingerpicking you may want to check out the acoustic song section here: https://www.guitartricks.com/songs.php?input=acoustic
If you find yourself getting frustrated or bored, I always recommend learning songs so you can put the skills you've learn to use.
If you have any questions, comments, or concerns, please contact us.
