I don’t understand

I don’t understand
 The simplest sound
 With four letters
 Whatever it was
 I’m over it now
 With eyer day
 It gets better, it gets better

Are you loving the pain, loving the pain
 And with every day, every day
 I try to move on
 Whatever it was, whatever it was
 There’s nothing now
 You changed
 New Age

I’m walking away
 From everything I had
 I need a room
 With new colours
 There was a time
 When I didn’t mind
 Living the life
 The simplest sound
 With four letters

Are you loving to pain me, loving to pain
 And with every day, with every day
 I try to move on
 Whatever it was, whatever it was
 There’s nothing now
 You changed
 New Age

Loving the pain, loving the pain
 And with every day, every day
 I try to move on
 Whatever it was, whatever it was
 There’s nothing now
 You changed
 New Age
