Any telly i watch these days I've downloaded, and some kind soul snips all the commercials out
But i do have a soft spot for the ads the OP is whining about. Local commercial radio is the traditional home of bastardised pop melodies... it's an art form. Almost.
One of my lesser played bits of vinyl is a Unipart album of advertising jingles. Imagine popular Beach Boys, Carpenters or Jan & Dean songs, but with lyrics like
driving to town, the car breaks down, i hope there's a Unipart dealer around... and if you think that lyricism's poor, wait 'til they shoehorn in the lyric
all Unipart parts are guaranteed by British Leyland.
Then there's my MP3 folder full of old Coca-Cola songs, performed by the artists themselves; Karen Carpenter, Neil Diamond, the Andrews Sisters, Everly Brothers, Moody Blues, Roy Orbison (and many more) all singing bastardised versions of their own hits, but with lyrics about how great Coke is.
...like i say, it's art, almost.
