Nice tips, all of them saved for the special moment when this happens again. :)
I friend just told me a tip that he read somewhere (not sure where) and I want to share it with you.
The tip is: analyze sentences and their rhythm, for example:
"Drag files here to attach, or choose files" (it could be any random sentence), which would be "drag-files-here / to / a-ttach / or-choose/files" (imagine musical figures of the pronunciation), then use that rhythm to create a melody with it. Not sure if it works, but I found it very interesting, at least it may obligate you to use a rhythm you didnt use before :)
Thanks mates for all your tips :)
