These are 31 of my favorite bands. The top 2 bands are the only bands that are in numerical place. I listed the rest but necessarially in that numerical order.
There other that I have missed putting on my list. But I listen to them, even if I haven`t listed them.

YOU know my list would have been similar and as long. thanks for doing all that work for me!
