I can personally understand not wanting to play one of your popular songs. In fact, i can understand it on several levels. Firstly, with me at least, sometimes i haven’t practiced a song in forever and someone requests it. On my own i have a shot at improvising past forgotten words and chords, but in a band setting you can’t very well all improvise, or know if anyone knows what to do without conferring first. Secondly, even if you know perfectly well how to play a song, sometimes it needs a little break. When i write a song i really like, within a year of its conception i usually go through a month of being totally sick of it. This period of time increases with every year that passes, until songs from half a decade ago will probably only get played once or twice a year, if even that. So, i don’t really blame Weezer for leaving out “Good Life.” Hell, when was the last time i played “Afterglow” for anyone?
