okay! Vocaloid time!
this one I think is really beautiful - Wrinkle performed by Gumi
This is so saccharine I might as well be diabetic, I love it - Rin Rin Signal performed by the Kagamine Twins (Rin and Len)
this is absolutely beautiful - One Hundred Years of Love performed by the one and only Hatsune Miku
always a solid choice - I heart performed by Rin
be warned this is a sad love song about when loved ones are away - Gears of Love performed by Gumi
This one is also somewhat sad love - Earth's Last Confession
I'm too lazy to translate the title of this so I'll just link it here -

this is cute as hell - Dreaming Leaf performed by Miku
This is about a love story but still very good - Fools Among The Stars. it's a 2 part song, so if there are 2 videos labeled VY1 and VY2 that's why
This one is slightly wistful/melancholy, but still very good - Childhood Blues performed by Gumi
same caveat as before but a little more feels - Ikanaide (Don't Go) performed by Yuki
More sad love - Last Night, Good Night performed by Miku
okay, moving on...
Every other song by The All-American Rejects. Half their songs are about lost love/shitty love and the other half are about love in general. or they're like Move Along.
there's also probably a few dozen show tunes I could name.
Good-old-fashioned Lover Boy by Queen, pretty self-Explanatory
Queen - Crazy Little Thing Called Love
Queen - Now I'm Here
quite a few Panic! At The Disco songs
Journey - Faithfully
Journey - Any Way You Want It
Led Zeppelin - Over The Hills and Far Away
Led Zeppelin - Going to California
Earth, Wind and Fire - September
Gorillaz' song On Melancholy Hill is a good one, but as the name implies it does carry a tinge of sadness
Maybe check out Mystery Skulls, but your mileage may vary with some of their (his? idk might be just one dude) work
A classic: Fly Me To The Moon
more Beatles songs than I can count, like All You Need is Love, I Wanna Hold Your Hand
Take On Me of course, but keep in mind that one may be
Blue Swede - Hooked On A Feeling
Redbone - Come and Get Your Love
Estelle Ft. Kanye West (yes I know its Kanye just roll with it) - American Boy
I'd say more for this but the title is some formidable Japanese and I don't feel confident in my ability to translate again

Asia - Heat of The Moment
Def Leppard - Pour Some Sugar on Me. basically just a sex song actually
Great Days from JoJo's Bizarre Adventure (yes it's an anime opening but it has a love theme if you see the lyrics)
