Music which was formerly described as "indie" music but has since received a great deal of coverage and exposure, resulting in an explosion in its popularity. Thus it is has become
mainstream indie or
mindie.
Also the kind of music that used to be played at
Mixed Bag, every week.
A few years ago it was rare to hear
Camera Obscura played anywhere, now they're really
mindie. They were even played in NEXT.
Mixed Bag is so disappointing. They don't even pretend to be indie anymore, all they play is the same mindie songs every week.
That band's so mindie now, they were on TMF!
