yep definately, myspace is amazing for pr. Seriously is. Ive had some great opportunities come my way with myspace playing a good part in it. I know u didnt think mass mailouts where the way forward but i know alot of peeps do think that so was just explaining in a little more depth really.
label wise i would honestly just say try the guys u really respect and have admired, think of some labels you would really love to be a part of and aim at that, which is what ur doing i can tell, sometimes it just takes another label or 2 before the ones you really want to hit take notice.
Luck plays a massive part too in the whole thing, ive gotten on to labels ive been collecting for years and would never of thought id end up releasing on them, and ive just had the pleasure of having the first release on a new label by an artist i respect hugely and we became friends a few years back, mutual respect a plenty and it's produced a wonderful opportunity for me which in turn has thrown up other great opportunities and offers for me
you'l be reet once you get some more info
dont wish to sound condescending by the way, i just happen to know alot about this kind of thing after a relatively short time releasing so far
