Yoasobi (but know them before Idol), Lia, LieN, Angela (The Japanese songstress) and l'arc~en~ciel Not on this order of preference, to difficult to choose who was in 2nd.

Wow, I haven't heard of a good amount of those! Definitely checking some songs of the others out, especially l'arc~en~ciel--I like the name and I'm always interested in checking out rock bands!
