Hey never feel bad for the next gen......my kids and my grandkids found their music.
I even like some of it ;-)
I found some myself.
If you go through the chaff to glean the grain, try J-Rock or J-Metal.
My favorite is Band-Maid. They just did in '22 their American tour. They came back from playing in NYC and LA for the opening band The Last Rock Stars this month. They are coming back for a US Tour in May. I have my VIP ticket for the Rockville concert in Daytona Beach.
They are not an Idol Japanese Band, but a true rock band. They all play their instruments, about as good as it gets. They write their own songs, all of them since 2016. I have not gone as far as some of the nuts but I did buy 7CDs and 3 Blue-Rays. The mixing and sound is superb particularly with Sennheiser 820s.
Live they sound even better......
Ohhhhh.......I forgot they are an all female band.......
