I used to have a really hard time lining up acapellas, but after a while of doing it you soon get the hang of it.
Using a program to beat map an acapella can be pretty awkward at times especially with an unconventional flow, experimentation is the order of the day. Unless you experiment you will never learn. There is nothing to be gained from a quick fix solution. When you get the hang of using beatmap software its a breeze, but sometimes you will need a reference copy of the original track to see what words hit on the kicks and snares and match yours to do the same. Tempo of the original is irrelevant as hearing hitpoints isnt dependant on knowing the tempo, that comes afterwards when you match the hitpoints you then learn the tempo.
