go ahead and throw it away.
if it's not fun, and it's not working, throw it out. DA threw out five songs before our first show, and we grew more quickly as a band because of it.
however, sometimes a part just needs a lot of work before it flourishes.
for example (link to DA's old myspace):
1. "Chums"- this song had maybe six or seven different versions live, and we played them all. the studio version here was a different beast, and the last several shows, we played as a quartet, with our friend orion playing a second guitar. this recording is my favourite thing I've taken part.
2. "the Phoenix" - this song started out with just my simple guitar figure that takes place throughout the first 2/3rds. I hated it. It felt stupid, and my bandmates talked me into sitting with it, and it eventually became the best song I think we'd done.
3. "Tos" - this was something I wrote on a four track in 98 or 99. we learned how to play it as a band in 01, had it recorded by 03. the band recording is missing a middle eight from the original four track version. This missing middle eight was turned into our other song, "Toos" and a different ending was created. "Tos" may be the most polished song we did, and "Toos" the most romantic. they all came from the same three or so ideas and took wildly different forms. In my current band, we have a version of "Toos" that is based around guitar instead of keyboard. It goes in a completely different direction too, but it's still the same idea.
4. "United Snakes" - this started out with Caroline playing the chord progression that is the song. i made up a bass line on my keyboard and she switched over to the crazy Juno sweeps, not playing her original part.
the amp clang that punctuates "snakes" in the verse came from a show in canada where we were on this piece of shit stage made longer by extending plywood across it onto a pool table. my twin was rattling on the plywood, and when I brought my foot down while singing "Snakes", it set the amp off. we loved it so much, we added it to the song. When Orion joined the band, we had him play a second drum kit on "United Snakes" live. I think it's the sexiest song we've done.
sorry for this wanky trip down amnesia lane, I know the most about stuff I've actually worked on. I just wanted to illustrate that there are dozens of right answers, it's just a matter of what works for the song. feel free to cannibalize your own work and hang on to the good ideas, or throw shit out if it's getting in the way of you moving forward.
do it.
