Basically, recommend any Vinyl/Octavia fics {Shipping or otherwise} that you enjoyed and you think someone else might like too.

If you just want to read some funny little stories about the duo, I provide these fanfics for you:

If you want something that's vert sweet and just cute, here's "Just Listen". http://www.fimfiction.net/story/257422/just-listen

And despite that thread I made a month ago, there is exactly one Mute Vinyl story I enjoy, and that would be "Broken Cellos, Broken Ponies". Vinyl's personality is more or less the same as her fanon self if a bit different {What with not being able to talk and all}, and she still gets some funny moments. The story is dramatic and fairly dark, but it does have a happy ending, though I understand if the dark stuff might turn you off from reading it. http://www.fimfiction.net/story/274494/broken-cellos-broken-ponies

4745480 I thoroughly enjoyed The Vinyl Scrratch Tapes. This fic is funny, heartwarming, and can be kind of depressing at times. it shows how two completely different ponies can find common ground and become the best of friends in the end. A lot of the characters make cameos. Though, I won't say who they are to avoid spoilers.

4745528 It's already in my Read It Later list, and I've read the first two chapters. It's a pretty funny story so far,

4745480 So far, there's only been two that I've read:

A Silent House

A Puppet To Her Fame

Personally, I think this story deserves more credit than it has been given:

A sequel was coming along, but the author decided to leave the fandom as she started it.

It sucks to see this happen to so many authors/fics that I like

I think I have only read 1 OctaScratch fic, I could use this chance to check some of this recommendations.

Aside from some of the big, older OctaScratch stories, I'd suggest Seamless:

It has a really good interpretation of Vinyl's character that you don't see often.
