I wouldn't use a single 128GB SD card, too much risk of it becoming 
corrupted, and then you've got to copy a new OS image and all the data 
back on to it, which for even a fast SD card is going to take hours.

Instead use a normal 8GB or 16GB SD card for the OS, and put all the 
data on a USB3 pen drive, which can be mounted as read only. USB3 is no 
advantage over USB2 in the Pi, but it will be hell of a lot quicker to 
copy the music to it from a PC.

If it was data which is likely to be written to, I'd also recommend a 
small SSD. But I'm assuming a music collection will be largely written 
in one go, and occasionally added to.
