Actually, those “recommended” (from where?) bitrates for music are relatively high and my hunch is that the average person wouldn’t see (hear) much, if any, difference with music ripped at a much lower rate. Years ago, I tested it out and couldn’t see (hear) a difference starting at a bit less than 192 kbps, for music. I also recommend ripping using VBR (variable bit rate) with a higher end at the top–it just makes sense to me, for the software to use more data space where it might be needed, and less space where it is not.
