i know what your saying i dont have an answer for you but what i do is export the beat to another program like acid or adobe and speed it up there and you wont have that prob
i name them whatever the first thing that comes to my head is at the moment and i get some strange names it makes it easy to remember with the date next to it that also helps
i just do it by ear hear the verse know the verse and ryhyme yourself with lyrics when it sounds like it goes then match it up dont think thats gonna help ya though but thats how i do it
