Apple is planning an announcement Tuesday morning regarding iTunes.

Count us among the cautiously optimistic. ITunes is one of the most successful software packages in history, installed on more than 125 million computers worldwide and used for about 70 percent of all digital-music purchases. (Exact numbers are hard to find, but it’s huge.) Its reach would seem to make iTunes a terrific platform for transforming the media landscape — if it weren’t such a bloated, hard-to-use, overloaded mess.

We don’t know what Apple will be announcing Tuesday morning (7 a.m. Pacific/10 a.m. Eastern). The Wall Street Journal, citing “people familiar with the situation,” says it will include the long-awaited coming of the Beatles catalog to the iTunes Music Store. It could be the addition of a streaming-media subscription service to iTunes. It might be an overhaul of Apple’s abortive attempt at a social network, Ping. Or it could be something completely different.

Regardless of what Apple does announce, here’s what we’re hoping for.
