Hi- the 'Cat is set up for HTML, which allows us to do some neat stuff when we know how. However, it also means we have to do some easy stuff the hard way. Instead of just a carriage return or hitting the "enter" key, you have to put an HTML line break tag at the end (or beginning) of each line. The tag is simple - it looks like this:

<br>

You can type lyrics in a word processor and use the "replace" function on your "edit" menu. Replace carriage returns with another carriage return, plus the line break, and then select "replace all." Good luck.
Holler if you need help.
