I had a lot more than I do now, but I forgot to back up my new collection before I formatted a couple weeks ago.
Amarok tells me:
Number of songs: 3464
Length: 1 week, 2 days
Size: Doesn't say
What's weird is Ubuntu tells me I have more songs than that. Selecting my music folder and clicking properties, it says:
Number of files, not songs, but I only have songs in the folder: 4237
Size: 17.6GB
* kotjze is confused now
