Obviously, it's each to their own, but I just don't see the point this type of album. If you're not going to write your own material, I'm, not interested. I know that rules out a lot of albums, but there's more than enough songwriters who write stuff I like.
I do have a few cover albums - Springsteen and Mellencamp - but in these cases it's more about the arrangements and playing than the songs. I know Bruce has a soul covers album out next month, and whilst he has more than earned the right to do it, I probably wont even listen to it, never mind buy it!
Rod Stewart on the other hand seems to do nothing but bland cover albums these days. I'm sure he was OK when he started out, but he's found a much better way of making money now and good luck to him.
