Just wondering, are there any solutions for songs with a non-constant BPM? And by that I don't mean songs which have more than 1 BPM, rather, fluctuating BPM. Two songs which I looked at and wanted to do were Stephen Speaks - Out of My League and Perry Como - Papa Loves Mambo. I felt pretty annoyed that they didn't have a constant BPM. Ditto for most live songs and orchestral music.
