This trend has been going for a few years now. Drippy singing accompanied by acoustic guitar or piano, singing cover versions of big hits in adverts really make my ears bleed! They sound awful & are so depressing. If there's any advertising execs out there bring adverts like the old Cadurys adverts, Tetley teabag men, something a bit jollier & easier on the ears!
If anything is guaranteed for me to mute the tv instead of take notice of the advert it's this. These adverts are the work of the devil..
