Years ago, purely because i liked the single 'Kiss Me' i got the album by Sixpence none the Richer'. Not only was the entire album awful, they also ruined 'Don't dream it's over ' by Crowded House . I played it once.
There must be many more (more credible) examples.
I am also guilty of still buying albums by long favourite artists, even though they are well past their prime. I feel obliged- ergo I purchased Depeche Mode's last cd, on the basis of thinking 'Wrong' was ok. Sorry, Dave, it was a painful listen. maybe I am just getting old
Not as the result of hearing a single, but as the result of hearing a track on John Peels show I have bought loads of albums, ranging from the unlistenable Terrorizer (other than one good song), through almost perfect pop (Pizzicato Five), satirical (Half Man Half Biscuit) to Grindcore (Carcass). I learned to have a pen and paper nearby when listening to Peel to write down the artiste, name of album and record label of anything I really liked. I don't think I've actually bought any new music since he died in 2004. Peel just played whatever he happened to like, which is why he was so popular. Well, to me anyway. That sounded better in my head!
Nor did I answer your question. The Terrorizer album. I heard one song, which was really good (if you like that sort of thing), bought the album, listened to it once and used it as an ashtray. It was unremittingly shit. Other than one song, which I had on a compilation.
I also used to listen to John Peel too- and vividlly remember his festive 50 in 1989- The Sundays 'Can't be Sure' was number 3. The following month I bought their debut album- still one of my favourites, so maybe that cancels out my dodgy purchases!
