Sure! Usually in the “Helpful Tips” area (top of a lesson page) I will state that the song uses specific techniques. This way, you could perform a search on the site for song’s that use those techniques.
So for example, if you are looking for songs that use hammer-ons, you could search for: “hammer-on” and this link would provide the results: https://rockclass101.com/?s=hammer-on
This song stuck out to me as a great starting point for working on hammer-ons and slides: Ukulele Duet
Let me know if you have any questions 🙂
