First of all, the construction and operation of this program is quite simple and well structured, but it has the decisive weak point, where such a program has always held ... no relevance ... I buy it today, it is already obsolete tomorrow. Too much is happening in this area ... there are any updates available, eg vieteljährlich, nor can one himself - and this point weighs even more difficult for me - write or add your own entries, add missing artist or group, in the absence of images upload yourself that ... that would be a super-program and would make a lot more fun, because then you can work with it. Thus, it remains an already outdated again Rocklexikum that while quite good works in its approach, but a lot more could have been made.
