got stuck with "sound of nations" (II)

I've noted a few lines for the verses:

verse 1:
take on the virtual journey
to places yet unknown
to find a world of music

Well, what now?

that steadily has grown (one syllable too few)
and leave your comfort zone (to be inserted as line 3, one syllable missing)
you'll never again feel alone (one syllable too many)

I've got to check with the music if and how I can match them.

verse2:
the music talks to people
who cannot talk themselves
- a universal language

Stuck again. "themselves" doesn't exactly offer rhyming choices in abundance, I tried:

choose music from the shelves (one syllable missing)
'bout tragedy and love and elfs (stupid, isn't it? And one superfluous syllable into the bargain)

I noted several words that might rhyme: shown, grown, own, flown.

And as rhymes for a discarded line "a world of music's waiting" I put down: gate, state, rate, relate, create.

That's how far I've got. The next step - as I mentioned above - will be listening to the music several times to get a better feeling for its intonation. Maybe six or eight instead of the required seven syllables could actually work. That depends largely on the stresses. For example "that steadily hahas grown" would not be viable whereas "that steadily has growhown" could be done only if the last syllable/note is unstressed.
