No, you're totally wrong. That app helped with thousands tracks without any word of lyrics at all. It compares sound wave with sample from database. And database updates every time with some new and old tracks, because some old tracks (1993) i haven't recognised a few years ago, but it find them today. I've found many progressive titles from Anthony Pappa sets, M.I.K.E. e.t.c. Sometimes you have to find some right part of the track, which shazam can recognise. Anyway it works and helps a lot. Database is big, actually it shows pictures from Amazon. So maybe it uses amazon database.
Also it can recognise wrong track, but you should try. And if it doesn't find title today, you should try some time later (6 months - 1 year).
Please help to identify these tracks:
ID 1, ID 2, ID 3, ID 4, ID 5, ID 6, ID 7, ID 8, ID 9 Acapella, ID 10, ID 11, ID 12, ID 13, ID 14, ID 15, ID 16, ID 17, ID Pack 1, ID Pack 2, ID Pack 3, ID Pack 4, ID Pack 5, ID Pack 6, ID Pack 7, ID Pack 8, ID Pack 9, ID Pack 10, ID Pack 11, ID Pack 12, ID Pack 13, ID Pack 14
