Well, you should not look for good songs, but for good producers and Vocaloids since all/most of their songs are good
My top5 in Prod/Voc:
1.) seleP (Check out my maps, Scarlet Rose, December 9th, Chloe, Marie Luise)
2.) HujuniseikouyuuP/FujuiseikouyuuP/Nanahoshikangengakudan (Most 0108 maos, like no,39, with a dance number, talent shredder, rubik's cube)
3.) Neru (Abstract nonsense, Ningen Shikkaku, Tokyo teddy bear)
4.) Bibuko (Reizouko mitara Oudding ga nai, Sorairo Gahou)
5.) Zips (Reiwai terrorism, Heisei Cataclysm)
1.) Lily (Best voice ever)
2.) Kagamine Len (really cute voice)
3.) Gumi (Weird voice, but after hearing 50+ songs of her I'm really starting to like her)
4.) IA (Probably on of the best vocaloids if you look at her songs, but she is still pretty good)
5.) Kaito (Some versions of him are terrible, but other are really awesome)
