Having gone to all the trouble of putting your music onto a PC hard disk, it's easy to get extra value by copying that music to an iPod for use outside the house.
An iPod can't play music files that are in the WMA format used by the jukebox. But the iTunes software, which is used for downloading music from a PC to an iPod, understands the WMA format. If you try to add the jukebox's WMA files to the iTunes library, iTunes will offer to make a copy of the files in a format that the iPod does understand. Not only that, but the title and artist information that is embedded in the WMA files is automatically imported into the iTunes database. You do need to wait for the format conversion to take place, and you do need to find extra disk space for the converted files to go, but other than that it couldn't be simpler. Having imported your files into iTunes, they can quickly and easily be downloaded through a FireWire or USB cable into the iPod for use outside the house.
Alternatively it's possible to use Media Center to convert and load the music into your iPod directly. That's what I do nowadays, but there are a few hidden snags, so I wouldn't necessarily recommend that course of action for everyone.
When making changes to artist and title information in Media Center, it's optional whether or not any changes you make are applied to the tags in the music files. If you're going to be importing those music files into iTunes or any other software, it's important that the "Update tags when file info changes" option is enabled.
