UltimateGuitar shows a fake tutorial video with the title of the song you're trying to learn. Clicking it just brings you to the sign-up page for their premium subscription.
I remember when U-G used to be good. You just downloaded the user submitted tabs and there you go. Now thing thry have are ASCII charts from 2010 and ads.
Songsterr is much better now, even if most of it's tabs are suspiciously similar to the same user submitted guitar pro files I remember from back in the day.
ASCII guitar tabs go back to the 1990s (at least). I wrote a couple out there that stayed in search engines top results for those songs for multiple decades.
