Sure i have, first of all i suggest you to take the whole album of those tracks
If you liked those, you'll surely like most, if not all of the songs contained in.
So, about vocals for those albums i can say you that the first album, contain 5 songs with lyrics, while for the second one the most are male vocals but still enjoyable. the third one doesn't have.
Now to show something
EDIT:
And here a try to give Butterfree an help for his music journey
Well it actually can't considered an help, more like a small support.
