do we really need a long essay with various factual errors?

also your edit is a mess and puts disco at the forefront of 70s experimental music, jesus christ

it's hard to be specific when you've just erased a number of major genres that "weren't even heard of in the 70s" when they were, to everyone else except for you, apparently

If there is any incorrect history, please be specific in what it is , & change only that part. If this is so incorrect that it needs to be replaced in whole, then it needs to be reverted to Version 1 or 2.

wow learn your music history first. of course these genres were around in the 70s D:

Tightened & corrected syntax, grammar, & punctuation. Removed some tags which cover music that wasn't even heard of during the 70s. Added tags.

Linked tags, artists and tracks using BBCode.

Added much more depth to the 70s background info.
