Oops sorry I didnt read your title well. I didnt see the "buying" word. That's why I suggested to buy them since most of the "good products" nowadays (Like GT) you have to pay to have it.
Indeed, they are hard to find those good "no hitters". I tried this morning to find you good music sheets of Orleans without success. I'll check at my local music store out of curiosity. A lot of time they surprised me by having sheets of songs that never made it big. Do you have a software to slow down songs like song surgeon for example? It helps me a lot to break down songs, at a faster rate.
There was a post not so long ago of someone asking is being able to read/write music was that important. I forgot who it was but here is the perfect exemple why it is such a great tool to have to being able to write in standard music notation. No need to buy or download tabs/sheets anymore.
Offcourse you need a fairly "opened ear" to translate on paper.
