android apps - Lyrics and track separation, key & BPM detection

[noobAudioJunky]

I've been playing with track isolation and separation on android using apps like bandlab. I recently discovered a similar feature in an app, where I was able to split the song into 2/4/?more tracks .. originally created thread to ask Which app this was (moises:) but edited to track audio adventures on Android...

(Bandlab and koala sampler are awesome )

bpm detection

Apps like Edjing and moises have bpm detection, but are there any apps that can analyse a group of tracks , and save BPM as metadata?

(Plan b is to use adb to connect android and use something like mediamonkey to analyse and write metadata)

Thanks!
