I often buy CD's in batches to save on shipping, so it can take me a while to get to them, but I play the whole disc if it's one I'm going to keep (I will bail on some cheap used ones which were musical "lottery tickets" if I decide I'll be movng it along). Streaming, I am generally just going to youtube for a single track I am in the mood to hear, or to sample something specific I haven't heard and am curious about. I don't borrow discs from the library (outmoded by streaming) and don't pay for downloads (have bought, I think, three downloads ever).
