Iowa State influenced my taste in music the most. In HS I was basically a top 40 listener... but some guys on my dorm floor introduced me to all kinds of awesome 'alternative' music... and I was hooked and have never looked back.
Holy ****, how could I forget about this? My first year at ISU was back in the early days where such safeguards didn’t exist for music and general network security, but there was an app that allowed us to browse others’ Shared Libraries in iTunes and download their music directly if we saw something we liked. It was like Kazaa or Limewire but without the malware.
So even though I didn’t know 100% of my dorm’s inhabitants I would wager that a good percentage of them indirectly helped to introduce me to some of my musical tastes that persist to this day.
