I'll connect the HDD to the Pi and export/import he library and hope it appears the way it does on the PC.

Remember music is different to video, the music library entries are populated by scanning the tags embedded in the music files. Export/import only applies to the additional info and artwork for artists and albums, and to song playback history (lastplayed, playcount and ratings). You will need to create the library first by adding music sources and scanning music files then either import the additional artist and album info (if exported to a single xml file) or allow scraping to pick it up from nfo files (if exported to nfo files).
