If they were 10 full songs, you'd be right. But they aren't. Most of those songs are the little dregs, bits here and here that the Beatles just hadn't gotten around to finishing, which is why they threw them all on as one big medley, smoothly going from one to the next. I mean, two of those songs are just a minute long, and another two 90 seconds!
The full 16-minute medley is cool and all, but I think $17 is just too pricey for what you get. I may still get it, just to have more to play, but I also might just get two or three full songs from the album and call it good.
