Our store has two active Electronics team members whom actually give a crap about the music browser. We keep it up as much as we possibly can and if there were different ways to organize it, we tried it.
For years (before me), the browser was simply haphazard. Everything was random, flow entered in and pretty much took cds by the handful and tossed them in and walked away.
I came in and for the first year or so, I tried to keep up with the 3x5s alone. Printing them, reorganizing, zoning, all back when the browser was still broken down into genres. The problem with this is that our general team members and the entire logistics team didn't understand how artist names worked. It was a whole lot of "is Taylor Swift under the T or S? It doesn't make any sense" or "is five finger death punch" under F, D, or P?"
It just reverted back to the old "I'm gonna stock all the product in the browser randomly" but this time with the respect of tossing random stock into the two stripped shelving spaces above the browser.
For the ease of everyone, save for the most sandiest of guests, we ultimately abandoned 3x5 white labels and simply went with the target planogrammed pre set locations and printed out standard labels. The only complaint I tend to hear from semi-reasonable people is targets removal of genres. Now things are stocked and located properly, nobody complains about 3x5s getting in their way, and guests can now see the price on every item.
Shelf labels work great for us and not only do they have the price but the artist title is also just high enough that the normal sized cd in front of it doesn't obstruct the title.
