PDF booklet for your MP3 album

I'm pretty sure I'm not the first person if have this idea in mind. I just want to write a few lines as a music lover. Legal MP3 album is great. You get it at home on the computer or wireless from your mobile device almost instantly after purchasing. It really saves you a couple things:

1. Gasoline to a record store
2. A few bucks cheaper than a CD copy
3. Plastic Wrapping/Bag + Jewel Case in most cases
4. Paper Booklets/Covers
5. CD
6. Space
7. Time spent on the traffic

It's delightful to have your music ready in a couple minutes and enjoy. I have one wish here. I don't think it's too much to ask for. Can I at least get a PDF booklet of the album??? It's nice to have one even just to look at the printed art.
