As previously brought up here, the Spotify app for mobile devices needs proxy settings like the desktop version or the ability to use the system proxy that is configured in the wireless connection.
Personally, using my mobile device at work forces me to use my mobile data for podcasts and music streaming, which has recently racked up the monthly data cost of my plan. Having the ability to authenticate through a proxy to a network alleviates this pressure on my data plan (and yes, this is ok with my place of employment).
