I really like burnout syndrome and spyair
Song recommendations are welcome
A friend also enjoys listening to Scandal and Necry Talkie.
Also, to Kenshi Yonezu
LiSA is great, so are Egoist, One OK Rock, Kalafina, and Aimer. If you like songs that dip into more unique tunes, I suggest Kalafina and Yuki Kajiura.
A more recent band I like is Wagakki Band. One OK Rock and Oral Cigarettes have some good songs.
This last one's J-chillhop but I love Nujabes.
