So I found this iPhone app called Simplify Media. It’s awesome. Now, even though my phone only holds 16gb of stuff, I can play over the air any song I want to hear from my computer at home. Granted, the audio quality isn’t quite as good as having the MP3 right there, and there’s a small delay as it buffers before playing, but the sound quality is comparable to maybe a mild-strength FM station perhaps, at least over the Edge network*. I haven’t tried it over 3G yet; maybe it’s better there? But it basically grabs a listing of files available on your PC (you can choose which folders), and makes them available to play on your phone, on demand. Genius. No more wishing I just had “that other song” with me. I’ve now got almost 10,000 more songs at my fingertips.
I guess you can also use it to share your library with others, though I haven’t tried that out just yet.
It was a free download for me, since I was one of the first 100,000 people to get it… I still haven’t yet found a need to actually purchase any apps; the free ones are pretty good so far. But this is the sort of app that I might actually have bought, as it’s that useful.
*[Edit: There is most definitely much better sound when streaming over Wifi or 3G as opposed to Edge, and almost no delay before the song starts playing. Awesome.]
