I won't buy a CD now unless it has songs on it I want badly enough that if everything else on the CD is bad, I can live with it. I went through a phase where I just bought stuff because I heard the band was good, or I kinda liked a song, or I liked a previous release or whatever and had more than enough disappointments. When we moved, I got rid of a whole shoebox of CDs, frankly not even worth the time to burn them before I sent them on their merry way.

......which coincidentally is an example of that very fact seeing as I bought the whole disc (liking prior stuff by KMFDM) and only liked that one track.
