You mentioned art block which makes me think you are talking about your own music you made, not published music that can be tagged and organized by artist and album. If that is the case, I suggest a serialized naming convention. It can be as simple as untitled100, untitled101, etc. For me it's easier to remember the number than it is to remember what "dhfhsijfjga" sounds like.
Not sure if this is what you mean but try using the software Easytag to change each of the files music tags in bulk. Not sure if it supports .wav files though
