Yeah, sometimes that stuff seems pretty shoddy. There are some CDs at a place I sometimes shop at of jazz artists who I dig that are kind of mini box sets where something like 6 or 8 of a particular artist's albums will be spread out over half that many CDs. They're on some kind of obscure seeming reissue label and a really cheap, like maybe only $12 or $15, but I fear they won't seem like such a great bargain if the music is poorly transferred and sounds like garbage. I may have to pick up one of these anyway, just to see whether or not the quality is as bad as I imagine it could be.
I was just listening to a local radio station and they were playing some very cool, vintage Ethiopian music. One thing sounded particularly bad, like an old scratchy LP, but I would bet that they weren't playing an old LP of this artist because that stuff is so rare to find in the US and were likely playing a CD that was cut from the only source they likely were able to find, an old scratchy LP. I don't even mind some music that was poorly recorded, often old international stuff, but stuff that was dubbed from scratchy LPs is much tougher for me to get into... though sometimes that's the only way we get to hear the music, so I get why it happens. CDs were really cool for this because you had a lot of stuff coming out which was older stuff from all over the globe, which would have been impossible to track down on LP, but now were being collected on this other format and were easy to track down and usually fairly reasonably priced.
