We don't socialize with this crowd. We think it's bullshit, and is just perpetuating the bland corporate rock that is killing the music industry.
It's bad business. If you're in the sonicbids game, fuck off.
We recommend some better alternatives:
Get your music to the right people with TAXI: The Independent A&R Vehicle that connects unsigned artists, bands and songwriters with major record labels, publishers, and film & TV music supervisors.
ArtistData help artists publish information to a variety of destinations with a single point of entry. Social networks, official websites, and much more.
Musicians - promote your band, win prizes, get music placed in TV or film. Music fans - enjoy FREE MP3s and streaming music!
A word of caution - even though the sites above aren't quite as full of scumfuckery as Sonicbids, beware of spending your hard-earned money on promotion through ANY web service, especially without doing a full and thorough analysis of what they might be able to do for you, and if it's worth it financially. These companies are in the business of selling dreams, and reaping the benefits of hungry artists willing to shell out for the promise of an opportunity. Most of them don't give a shit about you, or your music, they just want your money. And the ones that are big enough to actually have any sort of pull are such well-oiled pieces of machinery they have mastered the process of taking your money while providing you with the illusion of progress, without spending much effort, if any at all.
We don't use any web service or otherwise to promote our music. But if you feel that something like that might be right for you as an artist, please make sure to do your research!
