Is anyone planning on doing this or previously had it? I am pretty big into lifting and I refuse to do it without music. However I have always been adamant about keeping my music separate (I'm rocking the original iPod touch that first came out from Sept. 2007 ) from my phone usage, mostly because I think it will have an effect on the battery long-term, maybe I'm just too paranoid. Anywho I have spotify on my laptop and it is the shizz. How is the format on mobile? Does anyone plan on using their Nexus along with heavy music usage? Any feedback would be great.
