Music for designing

This is tough because I've got 3-4 songs I love and 200+ songs that I only remember when I hear them on the radio.

Right now, my "Top" list looks like:

1. "Search and Destroy" by Iggy Pop
2. "Poison" a remix by Groove Coverage
3. Something by Lady Gaga (changes each week)
4. And the same "Thunderstruck" song that the previous poster mentioned.

And then a million other songs I'll sing along to on the radio but can't name.
