brent I think all music players automatically run an indexer (it opens to populate from /home/music afaik)--
Yep. I created a symbolic link from /mnt/Music to Music in my /home directory. I just opened Museeks to see if it had the same problem, and it doesn't. It opened up with a page full of Bee Gees tracks, something my wife was listening to a while ago. No need to go read the entire library.
File systems (on Windows, anyway, and I'd bet on Linux, too) are able to trigger something to happen when something in a folder has been added, updated, or deleted. That's the only time an entire music library needs to be updated, in my opinion. Certainly not every time a music player app is started.
I might just start using Museeks more often. Elisa just displays album covers, and that's fine if you know what album you're looking for and it's not one of 7 album covers that look exactly alike. Then you need to load each album to see if it's the one with what you're looking for. For example, I have a set of all 9 of Dvorak's sympnonies on 7 CDs, and their covers are identical. To find the symphony I want to listen to, I have to just start opening albums until I find it.
I kinda like Museeks' way of scanning through the albums and showing each ones contents at the same time. And I like being able to double-click the first track and have it play the rest of the album.
