I find a loooooot of her songs sound better live than in studio. Well, maybe not necessarily "better", but more interesting.
I prefer almost any of her old songs when performed later with updated arrangements/vocals (I honestly cannot listen to WHATEVER unless it's the CDL 04/05 rip... omg, it makes such a huge difference.)
Songs that have really awesome extended intros/outros are also really fun to listen to - it's like getting more of a song you already love
momentum @ CDL 09-10 comes to mind, Heartplace @ PCDL, Don't look back + memories @ AT10, appears @ A MUSEUM/AT07, Secret @ AT07, etc.
