Firstly this is alot easier than people think, Here's how
1.Use different instruments,, listen to get lucky by Daft punk listen
Nile rodgers guitar
Then listen to John Newmans Love me again provided a link here

There exactly the same chords Bm | D | F#m | E and almost near tempo's too.
But of course you don't to change your sound that drastically, so keep your core tones the ones that make your sound then play around with your vocal deliveries, dynamics, drops and new sounding instruments to it. also change your
effects slightly.
2. Tempo's, a song played fast will sound different if played slow with a different melody ontop.
3. Change your strumming patterns, i use this term cause i play guitar, basically it means chop your chords to make them sound different, eg if you play 4 chords with no chopping then play them in a common reggae syle that will immediately transform the beat.
4. add more variation if in the first beat you played an A,B,C,D Major chord progression switch it to a B,D,A,C Major chord progression, or just play 3 chords and suspend the last chord use your imagination im not going to type all the possible combinations here.
5. Add something catchy or different to distract people from hearing recyled chords, even a funky bass lick after every 3 bars for example will do,
6. Change key, this is obvious if you play a 1.3.5 chord
progression in a C major scale that would be a C ,E, G CHANGE KEY to E,Same
progression you get E, G#, B
7. Use your imagination, and keep playing around with your old beats a few note changes and you have a fresh new one again
