My all-time favorites would be Taylor Swift, Paramore, Twenty One Pilots, Panic! At the Disco, Lorde, Avril Lavigne, Adele, and Queen. I love all their discography.
Lately I've been listening to Billie Eilish, Lana Del Rey, The Neighbourhood, The National, St. Vincent, Melanie Martinez, Marina and the Diamonds, LANY, The 1975, Dua Lipa, and Camila Cabello :)
