As you learn about Google's Android mobile operating system, which is run on the Google G1 phone (read Walt Mossberg's review from today), keep an eye out for music-related potential. One app I like is Compare Everywhere, which allows users to compare prices, create shopping lists and keep wish lists.

The app works by taking a picture of an item's UPC and looking up product information. While Compare Everywhere can be used for fast price comparisons, I think it will be valuable for finding information on albums while digging through a record store's bins or flipping through vinyl at a yard sale. Is the album worth the money? Is it from the band's misguided psychedelic phase? Who were the band members on the record? Compare Everywhere should be able to help, and it's well timed for the resurgence in vinyl.

As for the stock music functions on the G1, Mossberg says it comes with a "very basic" music player (no video player) and said the Amazon.com application as "works fine" (songs are downloaded over Wifi, not T-Mobile's network).
