Apple has been talking about the "Digital Hub" for a while now, and today they’ve delivered the centerpiece: iTunes. It’s based on SoundJam MP, which they acquired last year, but they’ve "Apple-ified" it into something much more integrated.
Rip, Mix, Burn
The marketing slogan says it all. You "Rip" your CDs into high-quality MP3s (no more carrying around bulky binders of discs), you "Mix" them into custom playlists, and you "Burn" them back to CD-Rs for your car.
The interface is classic Apple-clean, intuitive, and surprisingly fast even with a large library. They’ve solved the "metadata" problem by integrating with CDDB (Gracenote), so you don't have to manually type in song titles anymore.
Under the Hood
What's interesting to me as a developer is how well it handles the database of songs. Even with thousands of tracks, the search is instantaneous. It clearly uses a well-optimized indexing system under the hood.
// The iTunes workflow:
1. Insert CD -> Auto-lookup titles via CDDB
2. Encode to MP3 (or AIFF)
3. Manage library via XML-based metadata
4. Smart Playlists (The 'killer feature')
Outlook
Right now, iTunes is just a great jukebox. But I can't help but feel there's a bigger play here. With the rumors of an Apple-branded portable music player swirling, iTunes looks like the foundation for something much bigger. If they can figure out a way to sell music digitally without the friction of current services, they might just own the entire music industry. For now, I'm just happy to finally have a decent way to organize my MP3 collection.
