I use a Sansa MP3 player with 4GB capacity. This thing is very small, with a tiny TINY screen. Long names have to scroll horizontally. Internally, it organizes things based on their ID3 tags. Having the "album" tag of hundreds of files all say "JapanesePod101.com _ Basic Feed" is not very useful in finding things. Your company name is already in the "Artist" tag.
I have been changing the "Album" tags by hand, which is getting tedious. If you sent them out coded in the first place, to indicate which lesson collection they belong in, that would be a big help. I have been using names like
J Beginner
J Lo Intermediate
J Newbie
and so on.
If you did this, and then also removed the collection name from the start of each "title" tag, it would be easier for those of us with tiny screens to find things. So an item with a title of "Beginner Lesson #87 - Reunion III - Audio" would instead be "#87 Reunion III" with an Album tag of "J Beginner" and so on.
I put the "J" on the front to distinguish them from the musical albums. Anything short will do, but please not "Japanesepod101.com". That all by itself fills the screen from left to right. The idea is to be able to find the album I want without waiting for the useful part of the name to scroll into view.
