I know many of you will hate this statement and say I am being an old jaded metalhead...... I think part of the problem is how easy it is to discover music. It is a blessing and a curse..... You know how the "chase is better than the catch" (No Motorhead pun intended, well...ok...maybe)???? Back in the day people discovered bands from tape trading. I still have many tapes (somewhere in my crawlspace) of demos and bootlegs that I traded with people. Bootleg live recordings is how I heard a ton of bands for the first time. There was more of an effort to seek out these bands. (IE - finding ads in magazines, hearing them on local metal stations, tape trading, mail ordering a demo from a band, etc). Now, you can discover a band, and within 24 hours can come off as an expert in the genre. This is truly an amazing thing if you dive deep and discover something you like and stick with it. I think what is happening is just as fast as kids are discovering a new band, they are discovering the next trend.
