Lets try this in a thread. You list some stuff you like and hopefully someone can recommend something new for you to try and listen to.
I was listening to The Offspring, Bloodhound Gang and Blink 182 yesterday and now I think I should try find something new. Recommend me something O great Mewsicians.
Greenday, Stone Sour, Our Lady Peace, Breaking Benjamin, Sum41, Wheatus, Angels and Airwaves, 3 Doors Down, Weezer, 30 Seconds to mars, Everclear, Foofighters, Seether, Lit, Jimmy eat world, Thousand Foot Krutch, The All-American Rejects, Three Days Grace, Feeder
Well, based on the fact that 2/3 of your playlist there is made up of pop-punk bands and, before I delved to unarguably the best metal genre there is (metal) after my teenage years, I can recommend the following:
Fenix TX (especially their album Lechuza)
Lagwagon
Mad Caddies (if you don’t mind some ska in your punk)
