Not all of them are like that though? Your comment is really insulting to the groups who have worked hard and won it .
I didn't say all, lmao. However, a vast majority of the songs that won, while very successful in their own right, were not the best performing song that year. That alone is reason to not take those awards seriously, regardless of who wins or should have won.
The album awards are usually a lot more fair, at least over the last several years.
