Are these sentences correct:

1) I read your article like John's.
2) I listened to your song like John's.

3) I read your article, like John's.
4) I listened to your song, like John's.

I think in '1' and '2' the act was done in the same manner, and in '3' and '4', the manner is not the issue, and the idea is simply that the same thing was done.

Is that correct?

Absolutely none of those make sense to me. I can't even start to guess what meaning(s) you have in mind.

Thank you very much, Erik,

How about:

1a) I read your article as I did John's.
2a) I listened to your song as I did John's.

3a) I read your article, as I did John's.
4a) I listened to your song, as I did John's.

Gratefully,
Navi

Those versions are more comprehensible, though only barely. To make them better express the ideas you mentioned in your original posting, some indication of emphasis and/or rephrasing is necessary to get them to sound more natural and (in the case of the second pair) easier to grasp the intent of:

1a) I read your article in the same way I did [with] John's.
2a) I listened to your song in the same way I did [with] John's.

3a) I read your article, just as I did John's.
4a) I listened to your song, just as I did John's.
