In 'I'm a princess' I keep hearing an A chord in the verse but it's not just any A chord. It sounds likes it consist of these notes: A B C# D E. Correct me if I'm wrong but what chord is that?
sometimes it's A, sometimes it's Asus4, surely a lot of times it's Asus4(with 2). this should explain all 5 notes you mentioned, but probably not all 5 at the exact same time
