WykedPT,
I think it'd be safe for you to accept that ryan79's newbiwe status is just that & his suggestiojn, whilst quick and genuinely intended is seriously off the mark.
You should establish a presence to post at Soundclick, Reverbnation, or somewhere similar specifically set up to host music. Mspace, utub & fbook are useful social network & vid sites that can be handy for networking your music BUT the sound quality is poor to awful. I have accounts at all of these & more but post decent quality files for serious commentary & criticism at Sclick for streaming & megaupload for 320s to download.
You can upload 320 MP3s to megaupload, lightning MP3 or similar but, given you're new people are more likely to listen to you streamed music rather than download it - at least until you become kown on the forum.
Soundclick & Rnation allow you to set up an ongoing collection of tracks as well as details & contact info.
As Steenamaroo stated you'll also notice in the sticky at the top of the MP3 Clinic that HR now hosts uploaded MP3s - HOWEVER, there seems to be a teething problem or two so wait until that gets sorted in the meantime get a streamer happening & get known.
Have a squiz at my Sclick page in my signature links - that'll give you an idea of what's available.
