Music is everywhere.
Music is what drives us, what makes us happy. It is the lifeblood of most of us. In the 80's the rock music was at the peak of its popularity but gradually started to diminish as new trends were ushered in by the likes of Depeche Mode, Sabrina, and many more. Pop music became more popular because it was something new, something so different from what people had been accustomed to for so many decades.
Guitar riffs were replaced by electronic music. New and more modern synthesisers connected to computers, allowed its users to produce many fantastic sounds. From electronic heartbeat, rain to artificially generated guitar.
Nowadays, many young people are back on board with the new rock music. The heavy riff sound has been replaced with softener sounds. The bands are professional corporations. They do not form the way they did in the past, when a couple of guys would come up with an idea and start to play in a bar or out in the streets. Today corporations sweep through internet in a search of a perfect product to sell. They do not care about music.
If they see an opportunity in something, rock, pop, rave to name a few, they will do anything to make it profitable. Some of the old fashioned rock bands have been active for decades. Aerosmith, Rolling Stones, Scorpions they all have played for many generations of music fans, and they are not going to stop as they are as popular as ever.
Thanks to new technologies, they are able to keep their followers up to date on concert announcements, scandals etc.
