Every x days

I just found your shortcodes and it's almost exactly what I need. i was wondering if you'd care to add a little feature to it though.
would it be possible to have a recurrence based on a number of days what i set up, and not only weekly or monthly?
the idea is this: i am going to display a song of the day post. I have songs from 4 albums now and i will add others later. i can make a list of posts and set which would appear and hide on which day, but the recurrence would depend on the number of songs - currently 42. so I would need to repeat the cycle after every 42 days - and after every 52 days after the next album.
would it be possible?
it would also be a super freaking awesome neat feature if i could select a group of contents and display one of them randomly within a certain period - so we could easily make a post of the day, image of the week, etc. kind of thing. if you feel like it... :)

The first part of this I might consider building, but it needs some thought to think about how it can be implemented. The second part (random items) isn't really in line with the purpose of the plugin, so I probably won't build it, but I'm not completely discounting it at this point.

Thanks Dave, I appreciate it.
The way I see it, I would be comfortable using this new feature in this way:
[time-restrict-repeat type="interval" repeatday="42" lengthday="1" repeatstart="10-08-2015" display="show"]
In this case we'd specify that the type of repetition is based on intervals, and then repeat the display of the content for 1 day, every 42 days, starting with 10.08. I'm not native English so I assume you can come up with better names for these than I did :)
Additional parameters could be:

• repeattime - if the repetition could be more precisely expressed with hours and minutes
• lengthtime - if the amount of time the content remains displayed or hidden can be more precisely expressed with hours and minutes
• repeatend - if we want that the repetition stops at a certain date.
• display="show" or "hide", declaring whether I want to show this content in the specified time or hide it. If it is set to show, then in the remaining time the content would be hidden by default, and if it is set to hide, then the opposite.
  Well... This is how I see it, anyway. I thought it might help, give you some ideas maybe.

As for the randomizing, a lot of people I encountered would take good use of a properly created post of the day plugin (at least that's what they say anyway). Even though it wouldn't be the scope of this plugin, it might be a good idea to build one properly. It would make my job easier than the way I'd do it with your current plugin. I'd even give a few bucks for it and I'll be happy to help with my actual requirements. :)
Keep up the great work! Bests.
