What do you think of these lyrics i have written so far....?

Life without love .... its like rock and roll without drums
Life without love... its like seeing a rainbow with no colours

and thats it so far.. but i've got those towo lines to a cool tune

You have an interesting premise to work from.
Obviously, the topic of 'love' is a popular and recurring theme throughout pop culture.
It could be used successfully in a song as the chorus, ( Chorus is the repeating part, also sometimes called 'the refrain.')

Only criticism so far...
You should refine the rhythm so that is matches from line to line a little better..

for instance...
Life without love .... it's like rock and roll without a drummer
Life without love... it's like a rainbow without the colours

You do not have to use my particular revision as I'm sure you can invent your own. The object is to create a natural 'speech-like" rhythm that agrees with other stanzas in meter and number of syllables, It is also a good idea to have the stressed or 'accented syllables' at the same place in each line. This makes the lyrics more memorable, shows off your poetic mastery, helps train your poetic skill, and makes it MUCH easier to write an effective melody that fits.
