Uploading/playing mp3 files using Rails
<p>I'm working on my first "real" Rails project - "modernizing" an old website for a church choir and am building it in Rails.  They currently have a practice page with a list of links to mp3 files stored on their server.  I would like to store the mp3 files in a database and have created a model for the songs - title:string, part:string (tenor, soprano, etc), audio:binary (this is the mp3 file).  When I submit the form, the audio field is nil - the other fields save correctly.  Should I be using a Gem for uploading/saving the mp3 files?  I've come across CarrierWave, but have only seen it used with images.  I was under the impression that the binary field in active record was for preserving the original file format.  Thanks in advance!</p>
