I've spent some time scouring the internet for song sources. I have a program which converts Cell Phone Ring Codes to harp tab. I have adapted this so it works with either Chromatic or Diatonic harmonica.

630 Song Snippets. These were converted from Seimens ringtones and are usually short parts of the song which were intended to be used as phone rings. There are some unusual ones and quite a few rap songs. There are some Beatles favorites and some classical. I have arranged them alphabetically, but not by subject.
