I just recently uploaded my song "Now I Understand" at Garageband.com (after doing 30 reviews). I have gotten really good responses so far! My track is going to be featured as Power Pop song of the day on Saturday (the 17th). It jumped from #71 on the chart to #24 in just 2 days. I can't wait to get some more songs up on there. It is nice to get some actual useful feedback.
Do me a favor and go check it out on the 17th (or anytime really). Give a recordingreview brother some love:
