My ipod

So I was going through my ipod trying to make a playlist of my favorite music. I was going through all 300 songs and my "favorite" playlist ended up being 64 songs. What the heck? My favorites included songs from almost every genre of music, from heavy metal to musicals. I even had a country song in there. I don't know how to decide which songs are my favorite! It's like asking me what my favorite book is! (actually, books are worse!) I'm lucky my ipod is only 2G...Dane has an 18G iopd...he can fit 20,000 songs on it...I don't know what I would do with that much music!
