I do think things have swung into more live music realms at the moment but eventually it will start to swing back.. a few years ago there was no good rock or indie music about but i think there is a lot of good stuff now.
Thier scene got shit so they had to pull somthing out of the bag - which they did, and now its polularity has undergone a huge rejuvination.
According to the general pattern i notice in fashions and tastes i think dance/electonic music will hit a low and then pull somthing out of the bag itself and swing back after a few years... that is if its not too late by then and everyones making thier own music on some ultra high tech one-button-hits-the-spot ejay garage band type thing..
