It's admirable to maintain artistic continuity throughout your packaging, but don't toss legibility. I had to use a magnifying glass. And trying to even find the lyrics to all the songs proved fruitless. . . . The liner notes should have translations so that people who don't know French will grok the entire depth and dimension of what they are doing. And reviewers read them, even all the details of the guest musicians.
Consumers like to touch the product before the lay out the cash.
If a store isn't playing your CD, let them imagine what the music is like. Describe the music in a short sentence or two. They'll know by what they read. For example, Eversound Recordings list Max Music and Eversound. I can't tell you how many times I've reached for an album to fit a song into a set and then not knowing how long the tracks were and not having the time to clock each one, just passed on the album for something else.
