But surely, drums/percussion aren't just there to keep time?
They can be used as a solo instrument, and as an accompanying instrument - as much a part of a song as any other instrument, or vocal line for that matter.
To me, the question behind the OP is comparable to one having listened to a symphony and asking 'What's the point of the cellos'. It doesn't make any sense. The way I see it, if you write a song, you have a pretty simple choice - drums or no drums. End of story. Get over it.
It's a complete subjective non-argument, and for so lucidly pointing it out, I should hereby receive not only a 'Helpful' jobbie, I believe I am entitled to a 'Best Answer' and a free wowwipop.
All of which reminds me of a recent conversation I had... SidStrummerUK: Hey fatty, did you enjoy your holiday to Jamaica?
Straummy: Yes thank you. And I bought you a present back!
SidStrummerUK: A present!
Straummy: Oh yes - I brought you back some authentic Caribbean drums.
SidStrummerUK: Steel?
Straummy: No you cheeky fecker, I paid for them.
