.Evolving Music.

Ah, mobile music. How sad would our lives be without it?

First came the iPod that we all know and love, which made its predecessors (the Boombox, the Walkman, the MiniDisc, the MP3 player) look just…silly. Its many subsequent iterations became sleeker and cooler each time. Then the iPhone came along and more and more of us drank the Apple flavored Kool-Aid. With 3G and the rapidly expanding App Store, the iPhone has become a veritable phenomenon.

Despite ongoing issues with MobileMe, email, low battery life and more, the little phone machine is charging down its steep rocky path alone, leaving its competitors in the dust and getting better every day.

Random sidenote: Someone actually told me they were torn between the new iPhone and the new Blackberry. I told him that’s like saying you’re torn between Prime Rib and a Big Mac. (He bought the iPhone the next day.)

Combining your phone and your music player into one device was certainly a convenient first step. But now, with the App Store going nuts, more and more innovative music apps for the iPhone are popping up. Here are my favorites so far:

Pandora
Yes, I know. We rave about Pandora ad nauseum. But, quite frankly, they deserve it. What was already a killer service is now one of the leading iPhone apps. Sick of your own music? Hate the radio? Then open up Pandora at home, in your car, or in your earphones while you’re on the go and have your customized radio station at your finger tips. Remember, the more you use it the better it gets. In this case I say go ahead Captain Curious! Open up Pandora’s box and watch the magic unfold.

Shazam
How often do you find yourself saying “Wait, who sings this song?” You make a mental note to find out later and never actually do? Here is the answer to your dilemma. Open Shazam, let your iPhone “listen” to the song in question and it will tell you the artist and track name. Freaking great. I’ve also been using it as a way to effortlessly tag songs that I want to possibly download later, as I hear them.

SeeqPod
On the flip side of Shazam’s service, you have SeeqPod. You know the artist or track name but don’t have the song when you want it. Type it into SeeqPod and, boom, their crawler finds songs and videos for you. (We’ve mentioned them before too, as pioneers of a growing digital music trend – “playable search”.) So now, with SeeqPod on your iPhone, whenever a song pops into your head that you want to hear it’s there for you.

Midomi
Midomi is like Shazam, but with with more flavors to choose from. In addition to letting your phone “listen” to the song à la Shazam (Midomi calls it “grab” not “listen”), you can also sing/hum the tune, or say/type the song name. Very handy. Naturally, once you find the song you can buy it on iTunes, bookmark and share, watch YouTube videos etc. Watch the overview video here.

All of the above are easy to use, insanely practical, and really fun to have. But, for the more musically inclined among you, here are a few others worth checking out:

For musicians, there is Stay in Tune, TyroRuner (guitars only), and OmniTuner to tune your instrument on the go. If you want a mobile click track check out Orfeo or iMetronome. For DJ types, MixMeister scratch (cool concept, reviews not great though) and BeatMaker (see a review and video here).

And these are just the early apps. Imagine how prehistoric they will seem in a year or two…
