A week ago, on my blog, I proposed the thought of: with apps like Pandora, Last.fm, and Tuner (among a couple others), why even put music on our iPhones? Some thought it was a dumb idea, others embraced it. Before anyone spoke a word about it, I decided to challenge myself. The challenge: to not use the iPod app on my iPhone for an entire week, only getting my music from one of those three apps.

The first couple days of the challenge were naturally difficult. Switching from the tunes I normally listen to, to songs randomly picked due to their similarity to the artists I love to hear. By the middle of the second day, though, I was completely adjusted.

Sad to say, though, one thing that I wasn’t able to adjust to was the fact that I was on EDGE. Surprisingly enough, though, everywhere I was during the week I was able to get good enough signal (at least 3 bars) so that Pandora didn’t need to buffer during a song. The sound quality was great no matter what.

All in all, it would be smart to only put one or two hours of your absolute favorite songs (or what I call “emergency songs”). Then you’ll be able to use all the free space for apps, pictures, and videos. With 8 or 16 GB, that’ll end up being a lot of media. You’d definitely want to have the space whenever a good video recording app is released.
