Young T's musical recommendations

In our effort to get our youngest to bed, I've learned that he has quite the opinions about music. Sometimes, we can get Young T to fall asleep by watching music videos. His current favorite band seems to be The High Kings. They sing Irish folk songs. But he only likes some of their music. If I turn on the wrong song, he fusses until I change it. Occasionally, we mix things up with barbershop on youtube, but he tires of that quickly. He highly recommends "Paddy's Green Shamrock Shores", "The Irish Pub", "Marie's Wedding", and "Star of the County Down". But he doesn't prefer "Fields of Glory", "The Wild Rover", or "Galway to Graceland".

Do you have any recommendations? We need something new.
