Who are your favourite bands?

So Im sure a few of you are sad about TAI breaking up, but I was wondering, who are your favourite bands?
Mine are: all time low, Hey monday, paramore, versa emerge, we the kings, we are the in crowd, my chemical romance and greenday.
There are so many reasons why I love these bands that it's hard to pin point. I guess it's just because they have extremely talented people in them, who make amazing music that makes me feel happy. I'd be interested to hear why your favourite bands are your favourite too.
So just leave a comment telling me your favourite bands and if you send me a message with your favourite member of said band, I can write you a one shot involving them, if you'd like.
