Ehm... Finding correct BPM is fun, I think. When some kind of machine do that instead of you, maybe it is easier a lot, but it's less satisfaction from making a beatmap. That's my opinion though I think a good mapper should stand against this maybe the hardest task, and set the correct BPM. If it's really hard to do, there is thread like this one, to help, right?
I don't know, if somebody reading this forum to help, but anyway, I want to post here my map. It is Popped and needs just checking by another BN or QAT. I don't see any troubles with timing. Only in the first part of track (1 minute) beats sometimes late for ~2-5 ms, for lack of drums. It is instrumental song. Please check it as quickly as possible. https://osu.ppy.sh/s/326121 (Eluveitie - Isara). Thank in advance.
