There are some cases where covers of video game music get flagged. I would do a test upload to YouTube and check.
If it's fine, I would still give the performer credit.
If you'd prefer to use the original track, a large majority of video game music is safe to use. Stuff with vocals is more likely to get flagged, as is Castlevania: Symphony of the Night and certain Dance Dance Revolution tracks (for DDR, check iTunes, as well as whether it is a licensed artist). Avoid official re-arrangements of Final Fantasy music. I've also seen a small handful of Nintendo tracks in the system, I'd do a test upload for those too. Also do test uploads and give credit for music from indie games.
And after all that...

maybe shoot Jones a message with specifics to check it beforehand if you're really worried.
