I’ve never seen them listed out on a site – and it would be of very limited use anyway as you’d still have to look at the list, load your track, find the point they are talking about, and set the cue point. Not sure what time that would really save you, and with so many edits and remixes of songs out there, it would be hard to tell from a list if you were even looking at cue points from the same version that you have.
Now something that IS more helpful – some record pools send out their tracks with a few cue points in them. DJ City for example has Serato points in their tracks. That can save some time.
