upon investigation on the legal considerations you have to make before posting, uploading recordings on to your website. In class, we came across this website which is excellent..
one of the lines from the text says it all...Fair dealing with a literary, dramatic, musical or artistic work for the purposes of research for a non-commercial purpose does not infringe any copyright in the work provided that it is accompanied by a sufficient acknowledgement.
to me this means that when you post something that is undercopyright ie. a cover of the song you have done then you must make a reasonable mention to the artist/copyright holder.More investigation on this will be posted soon.
