We have two aspects:
- Price: It costs next to nothing to keep a spare sd card around.
- Restoring the system: Moode has excellent functionality for backup and restore
With these two aspects it doesn‘t matter whether you card dies every two years, you simply take the backup out of the drawer and continue. Use Moode as Tim intended and enjoy the music. As Ken said, you might consider a USB stick or an SSD drive
Here be dragons…
But if we look at evidence, then my experience differs from Tims and the others. I am someone who puts the hardware through a lot of stress and you shouldn‘t view my experience as „normal“. Example: I once turned an RPi on and off every 30 seconds for two weeks, after which the sd card simply quit.
And since I have a bit of background knowledge I know for a fact that a power loss can toast your sd card. This has become less and less likely with technology advances, so that today the probability for this catastrophic event (in the life of an sd card) is extremely rare. But it can happen as long as the sd card is mounted in a writable state. This state, though, is necessary for most normal operations and a Linux system in general is designed only for writable file systems.
Which means we have a dilemma. We can either go Tims way (which I would suggest) and accept the very low probability of the sd card dying, mitigating against it with the backup in the drawer.
Or, we can go OCD way and trick the Linux system into thinking it can write into its file system by putting all changes into RAM only. This means everything that changes during the normal operation, be it configuration, playlists, radio stations etc., is lost as soon as you turn off the power. On average, this might not be what you want. For me, this is fantastic, because on one hand I had the motivation to understand how to implement this with Linux, on the other hand I can now sit there with a smile and pull the plug on a Linux system. And trust me, this is exactly what I do (smile when I turn off the power).
So, TLDR;: Don‘t worry, simply use the system as Tim designed it.

PS: But if you want to go the OCD route, then I‘m more than happy to help :-)
