Guys bandAmp is like your granny , you love her dearly but god she can be slow sometimes and you need loads of patients with her ! 
Your allowed as many Favorites as you want, as with songs in your playlist and the links or the blog or e-mails, as many as you can.
You can upload as many songs as you please but you have to review 3 songs before you can upload ! But this you know I take it.
So if anything else is happening then it's down to bandAmp glitches !
Wait till you get the "MP3 not a valid file" or "You already have a song of this name" ....... then you REALLY get frustrated !
