I know what you mean. There's a metal band around here that is just DYING for me to join them. And it's honestly annoying the shit out of me. Every member of the band messages me on facebook like 5 times a day trying to get me to come play with them. If there was only some way I could get them to understand that every time they pester me they are hurting their chances of getting me. They are actually pretty good, but while I love metal, I like to do more. Of course the music I play is very metallic, but I like it to have influences of pop, blues, symphonic, and possibly even ambient all slapped on top of a metal base. (as you can probably tell). Of course, all my songs are covers as well, so far anyway, but I still try to do things original with them to incorporate all of my elements. If it's a purely metal song I want to cover, I will try to find a way to bring symphonic and pop elements to it. If it's a classic rock song, I find a way to heavy it up but also make it symphonic.
The real dealbreaker for me with this band that wants me is that they were always pestering me to write a song for them. Well I wrote one, and none of them can play it, and to me it isn't hard at all and I can't teach it to them. It's not that they aren't good enough to play it, I just can't seem to get through to them, and I learn songs extremely fast so I get impatient, and I don't want to be that guy that bosses and bullies the other band mates around, so I just feel it's best if I stay solo unless I can find somebody else that learns fast. Or I might just record the song myself and send it to them and maybe they will understand it. I know all this sounds like I'm an egostical, stuck up asshole but it's really not the case. I don't *want* to be condescending, and it's not so much that I play things better than other people, it's just that I can learn new things way quicker than most people so I have to fight really hard to not get impatient, and I don't want to be impatient with people.
I've been really into recording songs from the mega man games lately (as evidenced by the last song I just posted), because even though they are from nintendo and playstation games, they perfectly capture the feeling I like to create. They have a metallic base, but they have a symphonic edge and the melodies have lots of pop feeling. I love it.
