Query: Good deal for the money

There are tons of songs this book. It has some of my favorite songs, like Carol of the Bells, Oh Christmas Tree, etc. However, about 70 or 80% of the songs I've never heard before. I think they are "old school" songs with common melody. So, I'd say I really enjoyed about 20% of the songs, but the remaining 80% left something to be desired. I'm not a super piano player, but I'd say only a few songs were challenging to play, some songs were very simple, but most in the simple to average range.
