My own personal radio station

Got myself an iPod the other day and have been filling it with my music since then. When they first came out I wasn't sure what the point was but now I can see they're like having a personal radio station. Most folks are happy with a smaller playlist (less than 20 G) but weirdos like me and Ms Goat require more variety and depth. Last night, after I'd gotten most of my prog and hard rock all loaded up, I did my first shuffle of the 5152 songs (taking up 20 G) that I had on there and this is what the first 10 songs were:

Soundgarden: Fresh Tendrils
Rush: Time Stand Still (insert sound of Ms Goat groaning)
Genesis: Follow You Follow Me
Yes: Angor Wat
Hawkwind: Down Through the Night
Aphex Twin: iz-us
Randy Coven: Au Privave
Queens of the Stone Age: Everybody Be Happy
Audioslave: Seven Nation Army (live)
Air: Empty House

Hopefully 80 G will be enough space for me. I knew it was ok back when Ms Goat got hers but I've been acquiring a lot of music since then. I recall once thinking that if I had more than 400 CDs I wouldn't be able to know and appreciate them as well as if I had fewer. At some point I must have realized that my latest count is around 1200. Good thing hard drives keep getting cheaper...
