No, they're crucial.

Ew no

Most people misuse them anyway. Examples: "the 80's", "its so good", "the dog and it's toy", "lots of country's", and so on.

Apostrophes are only annoying when illiterate numbnuts use them improperly instead of appending a suffix or making a word plural.

Caught that edit nn

"It's" and "its" are not the same, so no.

y tho

Actually, the correct way is 80s' music, love.

The worst is when they use it with 'd to make a past tense, like deck'd

educate us

That would only be correct if you're talking about music from the year 1980. Decades are plurals. Plurals simply add an apostrophe to indicate it's a possessive.

Eek, that is a mess and a half.
