So this thing has been creating a bit of buzz lately, and this post isn't so much another case of linking to the videos (here), but my opinion on it.
I watched three of the episodes and I'm surprised about the attention it's getting. The concept of it is pretty common knowledge I thought. Everything is ripped off something else... refer to the Jimmy Corrigan/Family Guy post.
I'm not really a follower of Led Zeppelin, so I didn't realize how Led Zeppelin copied and did "covers" without crediting the other bands! I hate it when bands do that. The example of the beat from a Led Zeppelin song being sampled/copied was meh though, If you ever pay attention to drums or play drums, you know that the leeway for "copying" a beat is much more than a well known guitar riff. Tons of songs have the same beat.
So here's my contribution to "Everything is a Remix": How one of the main drum beats in death metal and the like is actually a polka beat (aka skank beat) and a really really fast polka beat (aka the blast beat).
The polka beat:
A metal song with a skank beat that turns into a blast beat later:
