With all the serious threads around, I thought I'd try to lighten it up around here. So what is, in your opinion, the best song ever? Note that I do not say, "favorite song". I want to know what you think is the best, not whatever takes your fancy presently. I don't care about genre's or anything. If you think some of Tchaikovsky's symphonies were the most brilliant pieces of sound you've heard, post it! For me, I'd have to say "Stairway to Heaven", by Led Zeppelin, is the best. It slowly builds up, becoming louder and louder until you reach the apex of the 8 minutes. It is pure brilliance of song writing. Slowly adding different instruments, with lyrics that can be interpreted differently, and abundant undertones for the listener who wants all he/she can get from his music. Listening hard nets you the bonus of being able to recognize the subtle synthesizer beats under the acoustic guitar. Then a brilliant transition to electric guitar solo near the end, climaxing, and fading off with a final line. Best. Song. Ever.
