I'm really struggling to unlock level 4. Up until this point I have learned everything relatively quickly. I'm not sure if this may just be the massive learning curve for me.

You can do it, try breaking up the song in smaller pieces to conquer. Off course it will get harder, but the more fun you will have learning to play those nice songs. Don't be frustrated if all goes a bit slower then when you started, that is normal, you are now learning how to play the bass!
