@Kelvo:
Dont know if going back to the past might actually be good. People might see this than as a lack of ideas, and that might again damage its succes. And looking at the charts raps are actually in fashion, look at Pitbull and co

One thing is sure, there is no real good manual to succes anymore, one just needs luck in this musical world of today and some famous co-stars like Guetta did, or some odd looking person, to gets peoples attention in this quick and fast changing world. The days of people sticking to one band forever are over Im afraid, now people want something new and fresh every year, hence the short-term big succeses of some bands and than the sudden silence of that same bands, well, lets cal it projects, because bands it arent anymore.....
