Dublin band Kodaline have tweeted Kellogg's about the similarities between their hit, All I Want, and music used in a new ad for the cereal company. Have a listen to both tunes and tell us what you think.
Taking to Twitter to voice their annoyance, the lads tweeted that nearly choked on their Cornflakes when they saw the ad.
The Dublin natives then posted several other tweets backing up their claims, including one from Voice of Ireland's Eoghan McDermott, and Elve8's Diana Bunici.
Kellogg's have responded by stating that the song in their ad is an original commission from Hush Music.
A spokesperson for the company also told The Daily Edge that they are "aware of Kodaline's comments on Twitter" and are "looking into the facts".
