Nice ideas,but rhyme is not the same as sound the same I think!

Rhyming link......and I got marked wrong for LINE.

Cheers but struggled with the songs.

Dirk - sounds like you had caps lock on. Do you think submitters need to add capitalized versions of all the correct answers too? 'Line' is definitely there as a correct answer.
UNIX - true, those would be homophones, but I wanted the answer to be easy to guess, so 'sound the same' and 'rhyme' both give you a correct result. I've had lots of grids where it feels like you have to be super careful what answer you give and feel cheated when I write the technically wrong thing.

Had the four punishments for basics. Even a pencil shoved up my nose. But that was unimaginative compared to what went on in some places a generation before. Ah, the good old days.
