If you like dance music you can check out Golden LUV by her also. As for her H!P stuff here are a few samples

Spoiler:

I tried to mix by like picking a ballad, standard j-pop song, rock, etc.

Uh if you are looking for a j-rock band you can try ULFULS. they are good



Oh Tomomi Kahala and Bonnie Pink are good too. For Tomomi her debut album LOVE BRACE is really good, her 10th anniversary best is great too (SUPER BEST SINGLES). As For Bonnie Pink my fave album by her is Even So. Like Tomo I would also recommend her best album if you want more of her.
