Ok so I am coming from the iphone side. I had about 900 songs on my iphone 4 and just came to the s3 but did not get them transferred to my new phone nor do I have them saved on my computer. So I guess my first question is should I go back to the verizon store and ask to transfer my music (i traded the iphone in). But I was thinking about just getting the songs over again but I was curious to what should my computer program I should input my music too? If it makes sense. I am highly technical. Custom built and go to a technology oriented school. I saw power amp. But is power amp as simple as getting songs downloading them and then syncing them to the phone?
