Visualizers are fine, but they shouldn't be taking one picosecond of time that Apple could be using to solve actual problems, that people other than stoned hippies actually care about, with the iTunes ecosystem.
It's a joke that, after almost a decade, iTunes still has no way to gracefully and simply manage music located on multiple drives.
My whole collection won't come even close to fitting on my MBP drive, but I do want substantial parts of it with me on the road.
As features on features have been added, iTunes takes up hundreds of megabytes of RAM and has become very slow to launch. With my collection of about 17,000 items, it also gets unresponsive every now and then.
The App Store, especially the updater, is not stable.
There should be a reasonable way of managing classical tracks, for which the "artist -> album -> song" paradigm almost never makes sense.
iPod syncing should be a systemwide service. It makes no sense whatsoever to sync contacts or calendars in iTunes. For that matter, video should also be in a separate app.
All of this matters 25,000 times more than an idiotic visualizer. Come on, Apple.
