iPhone music streaming. What's your preference?

TiPb did a cool post on the options iPhone users have when it comes to streaming audio. They covered many of the popular streaming applications and services offered on the iPhone platform. Included services are popular streaming radio applications like Pandora, Slacker, and Spotify, along with the native iTunes application which allows 30-second samples of songs and the ability to stream podcasts in their entirety.
They go as far as to mention music games like Rock Band and Tap Tap Revenge as a way for users to listen to songs on their iPhones. I would add the YouTube app because I know a lot of people who use YouTube to do a lot of their listening even on a computer. YouTube on the iPhone will of course only work if the application is open and the phone cannot be locked or playback will be paused.
TiPb also notes that mobile Safari can stream any music file from the internet that is supported by the iPhone. Typically embedded music streams are Flash-based and won’t work on the iPhone but in cases where the files are not reliant upon a Flash player Safari will stream audio in-app.
