Preparing your microSD card
Your whole library lives on the MusicBox's microSD card. That is the only storage limit: the number of playlists and NFC cards is not capped.
One thing to know before buying: the card must be formatted as FAT32, and the MusicBox will never format it itself. A card it cannot read simply will not mount.

Which card to buy
Between 8 and 32 GB, Class 10 or U1. That is the recommended range, and it is also the range that ships already formatted as FAT32.
With a 32 GB card and MP3 at 192 kbit/s you store roughly 370 hours of audio, more than 450 albums. That is far more than a child's bedroom needs.
Above 32 GB, cards are sold as exFAT, which the MusicBox does not read. You then have to reformat them to FAT32 yourself, which Windows does not always offer.

On Mac
Open Disk Utility, select the card in the left column, click Erase and choose the MS-DOS (FAT) format. That is what macOS calls FAT32.
- 03
On Windows
Right click the card in Explorer, then Format, and choose the FAT32 file system.
Windows only offers FAT32 up to 32 GB. Above that you need a third-party tool.

On Linux
Find the card, unmount it, then format. Replace sdX with the real name: picking the wrong disk erases the wrong disk.
lsblk sudo umount /dev/sdX1 sudo mkfs.vfat -F 32 /dev/sdX1
