First off, I've been doing this for a long time now. I still listen to a lot of the bands I've found by doing this. It's really simple, but it works like a charm. I ALWAYS find cool new stuff -- sometimes even bands that have been around 10 years that I never heard of.
The things you need:
- (Optional) A file sharing program (I use limewire)
- A browser. :]
1.) Pick one of your favorite bands.
2.) Go to amazon.com or cdnow.com (same thing)
3.) Look up that band's name
4.) Scroll down until you see "Customers who bought this title also bought:"
5.) Browse through the artists you've never heard of in that list.
6.) Check out one of their albums, preferably the one with highest rating (in stars)
7.) Either listen to the samples on amazon or download a song by them with your filesharing app.
If you like what you hear, repeat steps 3-7 using the new band's name.
You'll find TONS of new music you never thought existed.
It's a really simple way to find stuff, and I'm sure lots of you probably already do this. But for those who don't -- you'll thank me later. It works wonders. :)
