I tried my best to put songs from Memorial address to Party Queen in certain balance but I think it didn't really work well. XD Oh well, I did it anyway and that's good enough.
I added albums where these are in in case there are actually fans who haven't heard these songs yet. Also, all of these songs here are in my Top Ayu Ballads list.
