This is exactly what's happening right now. Many of my friends who were hardcore LP fans now don't follow the band a lot. A lot of things have changed. A few years ago when I spoke the name of Linkin Park, everybody was saying "Oh I've heard they're a great band! Will you copy their songs on my flash drive?". But now it's like "Linking Park? Who are they? Are they the band that had a song named... ah... oh, Burn It Down?"
I haven't seen any hardcore LP fans for a long time (except here). I think we have to deal with it. It is what it is.
