It may be a strain on your data plan, but if you're at home or the office, just use wifi.
The point of the fact is, if 16GB isn't enough, they make you buy the 32GB phone. If that still isn't enough for you, they recommend you use their services and apps to fill in the gap.
To the OP, may I offer a suggestion:
Use a large portion of your internal storage to store the albums/tracks you listen to w/ the most frequency, and leave the online storage for the remainder. Obviously you can swap between the two whenever you'd like, but seems like it would make the most sense given the fact that you still decided to go w/ a N5.
May not serve your "any track, any time, anywhere" purpose fully, but will save you data and still allow you quick access to a good portion of your media.
