Add songs and videos to iPhone without clearing library

If you're on another Mac and want to sync a song/video to your iPhone, iTunes will clear your Music/Video Library. But the iPhone syncs Podcasts separately from the Music/Video Library, which means you can use Atomic Parsley to rewrite some flags on your songs/videos, and iTunes will sync the song/video as Podcasts without touching your Music/Video Library.

So, grab Atomic Parsley, and run it with these modifiers (URL and GUID can't be blank):

... --podcastFlag true --podcastURL 'www.google.com' --podcastGUID '0000'

Now drag your song/video over to iTunes, and it'll show up as a Podcast and sync without touching your Library. Friendly note: The Podcast will show up by Artist metadata or podcastURL. This hint inspired by the methods covered in this one.
