technically, this is the usual he4rty quality (=excellent)
i like the last one best
the only thing i dont like so much is, that all the pictures show a format that is an anachronism
while the depiction of cassettes has been fashionable for some time now, its at the same time quite ironic that a yonger generation is fascinated by something, they havent got any contact with
all my younger work collegues laugh at me when i call my mp3 player a walkman
on the other hand its quite a tough challenge coming up with something different than the classic interpretation of the concept "mixtape"
layered, slightly overlapping waveforms might be an alternative idea
or the tracklist, which is a part of every good (recorded) mix
