This actually works pretty well. A new app called Seamless solves the problem of interrupted music when leaving your room by gradually lowering the volume on your Mac and raising it on your iPhone as you walk away (the volume is not distance-based, although that would be an awesome feature if it were). The app costs $1.99 and requires that the Seamless app also run on your computer simultaneously (the app is free through the Mac App Store). [via]

One thing to note if you are trying this out, is that the song being seamlessly transferred between the two devices must be present on both your Mac and your iPhone’s music library. For some, I’m sure that’ll become an issue, but I don’t mind it. It works as advertised and it’s great to not have to stop my music halfway when I’m leaving for work in the morning.
