Well, i can download the mp3 very easy but there is onething i can't do.
about the time start and stop of the mp3 file i want download, i see an option that can trim the mp3 and download it.
but after i chose a time of start and stop of the file, i click to download mp3 format file, but what it appear is the whole file.
The video i watch was about 30', and its size was about 200mb, i just need an 1' of it, waiting for download an 200mb file and trim it after download is so troublesome.
I hope you can help me answer this.
btw my english is not good, so sorry if it hard to understand.
