I've been using YouGrowPromo for over a year now and run 5 song promotions (all the Rising Star level promotion). They are true to their word in that you will get between 10,000 and 20,000 streams for your song. The reason I'm writing this review though is because of a recent experience i had with them. My latest song had a bit of a lackluster start in that for the first month, the two playlists playing my song didn't really run it very much. I approached my promotion person for that song (Rodrigo) and told him my concern and he was on it immediately. He got another playlist to take the song and it really took off! I was pleased. But then that playlist started to slow the song down after a month even though it was really doing well and getting lots of saves. Once again I contacted Rodrigo and once again he went to bat for me and got the playlist to carry on with the song. I think that's very good service and I'm quite pleased! I should add that one of the playlists has continued to spin my song long after the promo ended so I'm also pleased about that. If you want to get your song heard by real listeners and use a firm that goes to bat for you I would highly recommend YouGrowPromo!
