I absolutely suggest Epica, Garbage, Nightwish and Delain since I love female vocals.
I recently started listening to these groups and they're flawless. Check them out ;D
Thanks for the message. In the past I have listened to Garbage a lot and I will listen to the bands you recommended. This playlist is dedicated to emerging musicians, with few listeners. A kind of my personal bets on the future.
The first 4 songs to reach a thousand listeners in 2020.
