They chose to be commercially popular. They CAN absolutely shred, they ARE very talented. But they chose the top 40 route and are laughing all the way to the bank.
Everyone has a price, if you’re an artist and you havent “sold out” its because nobody offered you enough money.
The “sold out” thing bothers me sometimes, yes the ARE bands who come from less popular genres towards more mainstream sound because thats where they found commercial success and wanted/needed that money to keep doing what they do.
But there are also many bands who change genres and sound over time and some bands just enjoy playing that kind of ‘radio friendly’ music. Personally i feel like nickleback are in the ‘we just like this kind of music’ category.
(Personally I cant stand nicklebacks genre, so no bias here)
