I always do this. I buy an album on impulse having only ever heard one track from the record. Have to say though - 4 out of 5 times i get it right and I was so right with this one. I based my judgement purely on "Run" - the only track that most people who don't own the album know - and the rest of the album definitely doesn't let you down.
I've listened to it 3 times all the way through and it already feels like I've owned it a lifetime. A good place to be with any record i think.
Other impulse buy albums that I've had for months, years even, i still haven't bothered to listen to them all the way through because the first half was so awful.
"spitting games" is amongst one of my favourites on the album, along with "Somewhere a clock is ticking" and of course "Run", to name a few. If you're the kind that believes that "Run" was boring, then i wouldn't recommend this album for you, as that is their style and there is a thread of that throughout the album, with different slants, different sounds and different tempos. If, however, you love "Run" then i suggest you buy this record sharpish. Enjoy!
